How does spleen size vary with weight and gender. What are the normal dimensions of a healthy spleen. When should you be concerned about spleen enlargement. How is spleen size measured and evaluated.

The Spleen: A Small but Vital Organ

The spleen, a compact yet crucial organ nestled behind the stomach and beneath the diaphragm, plays a significant role in our body’s defense system. Despite its relatively small size, the spleen performs several essential functions that contribute to our overall health and well-being.

Key Functions of the Spleen

• Blood filtration
• Removal of old or damaged red blood cells
• Support of the immune system
• Production of lymphocytes

One of the spleen’s primary functions is to act as a filter for the blood. It contains a complex network of narrow tunnels that trap and remove old, damaged, or abnormal red blood cells from circulation. This process helps maintain the quality and efficiency of the blood supply throughout the body.

In addition to its filtering role, the spleen also plays a crucial part in supporting the immune system. When harmful microorganisms such as bacteria or viruses enter the bloodstream, the spleen, along with lymph nodes, produces lymphocytes – a type of white blood cell responsible for creating antibodies to combat infections.

Normal Spleen Size: Factors Influencing Dimensions

The size of a healthy spleen can vary considerably from person to person, and several factors contribute to these variations. Understanding these factors is essential for accurately assessing spleen size and identifying potential abnormalities.

Gender Differences in Spleen Size

Research has shown that gender plays a role in determining spleen size. Generally, women tend to have smaller spleens compared to men. This difference is attributed not only to the fact that men are typically taller than women but also to physiological variations between the sexes.

A study published in the journal Radiology suggested that men generally have a greater red cell mass than women, which may contribute to their larger spleen size. This finding highlights the importance of considering gender when evaluating spleen dimensions.

Height and Its Impact on Spleen Size

Height is another significant factor influencing spleen size. Taller individuals tend to have larger spleens compared to shorter people. This correlation is observed across both genders and is an important consideration when assessing whether a spleen is within normal size parameters.

Age-Related Changes in Spleen Size

The spleen, like many other organs in the body, undergoes changes in size throughout an individual’s lifetime. During childhood and adolescence, the spleen grows along with the rest of the body. However, once adulthood is reached, a interesting trend emerges:

• The spleen tends to shrink slightly with each passing decade
• This gradual reduction in size is considered a normal part of the aging process

Understanding these age-related changes is crucial for healthcare professionals when evaluating spleen size in patients of different age groups.

Average Spleen Dimensions in Adults

While individual variations exist, there are general guidelines for what is considered a normal spleen size in adults. These measurements provide a baseline for medical professionals to assess potential spleen abnormalities.

Typical Adult Spleen Measurements

• Length: Approximately 5 inches (12.7 cm)
• Width: About 3 inches (7.6 cm)
• Thickness: Roughly 1.5 inches (3.8 cm)
• Weight: Approximately 6 ounces (170 grams)

It’s important to note that these measurements are averages, and slight deviations from these figures are not necessarily cause for concern. Healthcare providers take into account various factors, including an individual’s height, weight, and gender, when assessing spleen size.

Spleen Size in Children: A Developmental Perspective

The size of the spleen in children varies with age, reflecting the organ’s growth and development throughout childhood and adolescence. Understanding these age-related changes is crucial for accurately assessing spleen size in pediatric patients.

Upper Limits of Normal Spleen Length by Age

A study published in the American Journal of Roentgenology provided insights into the upper limits of normal spleen length in children up to 15 years of age. Interestingly, the research found relatively little difference in spleen size between boys and girls within the same age group.

The following list outlines the average maximum spleen length by age:

• Newborns: Up to 6.1 cm
• 3 months: Up to 7.0 cm
• 6 months: Up to 7.7 cm
• 12 months: Up to 8.3 cm
• 2 years: Up to 8.8 cm
• 4 years: Up to 9.3 cm
• 6 years: Up to 9.8 cm
• 8 years: Up to 10.3 cm
• 10 years: Up to 10.8 cm
• 12 years: Up to 11.3 cm
• 15 years: Up to 11.8 cm

These guidelines help pediatricians and radiologists determine whether a child’s spleen falls within the normal size range for their age group. However, it’s essential to remember that individual variations can occur, and these figures should be used in conjunction with other clinical assessments.

Detecting Spleen Enlargement: Diagnostic Approaches

Spleen enlargement, also known as splenomegaly, can be a sign of various underlying health conditions. Early detection and accurate assessment of spleen size are crucial for proper diagnosis and treatment. Healthcare providers employ several methods to evaluate spleen size and determine if enlargement is present.

Physical Examination

During a routine physical examination, a skilled healthcare provider can often detect an enlarged spleen through palpation. This hands-on approach allows the doctor to feel for any abnormal enlargement or changes in the organ’s texture.

Blood Tests

Blood tests play a vital role in assessing spleen function and identifying potential causes of enlargement. These tests typically include:

• Complete blood count (CBC) to check levels of red blood cells, white blood cells, and platelets
• Liver function tests
• Tests for specific infections or autoimmune disorders that may affect spleen size

Abnormalities in these blood tests can provide valuable clues about the underlying cause of spleen enlargement and guide further diagnostic efforts.

Imaging Techniques

Various imaging methods are employed to accurately measure spleen size and assess its relationship to surrounding organs. These techniques include:

1. Ultrasound: This non-invasive method uses sound waves to create real-time images of the spleen and other abdominal organs.
2. Computed Tomography (CT) scan: Provides detailed cross-sectional images of the abdomen, allowing for precise measurements of spleen size.
3. Magnetic Resonance Imaging (MRI): Offers high-resolution images of the spleen and surrounding tissues without using ionizing radiation.

Among these imaging techniques, abdominal ultrasound is often the preferred method for evaluating spleen size due to its accessibility, lack of radiation exposure, and ability to provide accurate measurements.

Ultrasonography: The Gold Standard for Spleen Measurement

Abdominal ultrasonography has emerged as the gold standard for assessing spleen size due to its numerous advantages. This non-invasive imaging technique offers real-time visualization of the spleen and surrounding structures, allowing for accurate measurements and detection of abnormalities.

Advantages of Ultrasound for Spleen Evaluation

• Non-invasive and painless
• No radiation exposure
• Real-time imaging capabilities
• Cost-effective compared to other imaging modalities
• Widely available in most healthcare settings

During an ultrasound examination of the spleen, a trained sonographer or radiologist uses a handheld transducer to send high-frequency sound waves through the abdominal wall. These sound waves bounce off the internal organs, including the spleen, and return to the transducer, creating detailed images on a computer screen.

Spleen Measurement Techniques

Ultrasound allows for precise measurements of the spleen’s dimensions, including:

1. Length: Measured along the organ’s longest axis
2. Width: Taken at the widest point perpendicular to the length
3. Thickness: Measured from the anterior to posterior surface

These measurements provide a comprehensive assessment of spleen size and shape, enabling healthcare providers to identify any abnormalities or enlargement accurately.

Interpreting Ultrasound Results

When interpreting ultrasound results, radiologists and clinicians refer to established guidelines for normal spleen size. While slight variations are common and not necessarily cause for concern, significant deviations from these norms may indicate underlying health issues.

According to recent studies, the following criteria are often used to classify spleen size on ultrasound:

• Normal: Maximum length less than 11 cm
• Moderate splenomegaly: Maximum length between 11-20 cm
• Severe splenomegaly: Maximum length greater than 20 cm

It’s important to note that these guidelines may vary slightly depending on the specific population and the ultrasound equipment used. Healthcare providers consider these measurements in conjunction with other clinical findings and the patient’s individual characteristics to make an accurate assessment.

Beyond Size: Additional Insights from Spleen Ultrasound

While measuring spleen size is a primary objective of abdominal ultrasonography, this imaging technique offers valuable insights beyond mere dimensions. Ultrasound examination of the spleen can reveal important information about the organ’s structure, texture, and potential abnormalities.

Assessing Spleen Texture and Echogenicity

Ultrasound allows healthcare providers to evaluate the internal structure and echogenicity (sound wave reflection) of the spleen. Normal splenic tissue typically appears homogeneous with a uniform echo pattern. Changes in texture or echogenicity may indicate various conditions, such as:

• Inflammation
• Fibrosis
• Cysts
• Tumors or masses
• Infarction (areas of tissue death due to reduced blood supply)

These textural changes can provide important clues about underlying health issues, even when the spleen size remains within normal limits.

Detecting Focal Lesions

Ultrasound is highly effective in identifying focal lesions within the spleen. These lesions may include:

1. Cysts: Fluid-filled sacs that appear as well-defined, anechoic (black) areas on ultrasound
2. Hemangiomas: Benign vascular tumors that typically appear as hyperechoic (brighter) lesions
3. Abscesses: Collections of pus that may appear as complex, hypoechoic (darker) areas
4. Metastatic tumors: Secondary cancerous growths that can vary in appearance depending on their origin

The ability to detect and characterize these lesions is crucial for accurate diagnosis and appropriate treatment planning.

Evaluating Blood Flow

Color Doppler and power Doppler ultrasound techniques allow for assessment of blood flow within the spleen and its surrounding vessels. This information can be valuable in detecting:

• Portal hypertension
• Splenic vein thrombosis
• Abnormal vascular patterns associated with certain tumors

By providing a comprehensive evaluation of spleen size, structure, and blood flow, ultrasound plays a crucial role in diagnosing and monitoring various splenic conditions.

When to Be Concerned: Recognizing Spleen Abnormalities

While slight variations in spleen size are common and often benign, significant enlargement or other abnormalities can be indicative of underlying health issues. Understanding when to be concerned about spleen abnormalities is crucial for early detection and timely medical intervention.

Signs and Symptoms of Spleen Enlargement

An enlarged spleen may not always cause noticeable symptoms, especially in mild cases. However, as the spleen grows larger, individuals may experience:

• Pain or discomfort in the upper left abdomen
• Feeling of fullness, even after eating small meals
• Fatigue or weakness
• Easy bruising or bleeding
• Anemia
• Frequent infections

If you experience any of these symptoms, particularly if they persist or worsen over time, it’s important to consult a healthcare provider for evaluation.

Common Causes of Spleen Enlargement

Spleen enlargement can occur due to various underlying conditions, including:

1. Infections: Viral infections (such as mononucleosis) or bacterial infections (like syphilis)
2. Blood disorders: Leukemia, lymphoma, or sickle cell disease
3. Liver diseases: Cirrhosis or portal hypertension
4. Autoimmune disorders: Lupus or rheumatoid arthritis
5. Parasitic infections: Malaria or leishmaniasis
6. Cancers: Both primary splenic tumors and metastatic cancers

Identifying the underlying cause of spleen enlargement is crucial for determining the appropriate treatment approach.

When to Seek Medical Attention

While not all cases of spleen enlargement require immediate medical attention, certain situations warrant prompt evaluation:

• Sudden, severe pain in the upper left abdomen
• Signs of internal bleeding, such as lightheadedness or fainting
• Fever accompanied by abdominal pain
• Unexplained weight loss or night sweats
• Persistent fatigue or weakness

If you experience any of these symptoms or have concerns about your spleen health, it’s important to consult a healthcare provider. Early detection and treatment of spleen abnormalities can help prevent complications and improve overall health outcomes.

Treatment Approaches for Spleen Abnormalities

When spleen abnormalities are detected, the treatment approach depends on the underlying cause and severity of the condition. In many cases, addressing the root cause can lead to a resolution of spleen enlargement or other issues. Here are some common treatment strategies for various spleen-related conditions:

Treating Underlying Infections

For spleen enlargement caused by infections, the primary focus is on treating the underlying infection. This may involve:

• Antiviral medications for viral infections like mononucleosis
• Antibiotics for bacterial infections
• Antimalarial drugs for parasitic infections like malaria

Normal Spleen Size Depends on Weight and Gender

Overview

Your spleen is a small but hard-working organ hidden behind your stomach and under your diaphragm. It acts as a filter for your blood. Old, damaged, or abnormal red blood cells are caught in a maze of narrow tunnels within the spleen. Healthy red blood cells easily pass through the spleen and continue to circulate in your bloodstream.

The spleen can also filter out certain bacteria or viruses from your blood in support of the body’s immune system. When a disease-causing microorganism enters the bloodstream, your spleen and lymph nodes produce lymphocytes, a type of white blood cell capable of making antibodies to fight infections.

Unlike most other organs in your body, your spleen changes in size throughout your life — usually in response to illness or injury. A viral infection, such as mononucleosis, or a bacterial infection, such as syphilis, are among the conditions that can lead to an enlarged spleen.

The size of a normal, healthy spleen can vary considerably from person to person. Your sex and height can also affect its size. In general, an adult spleen is about 5 inches long, 3 inches wide, 1.5 inches thick, and weighs about 6 ounces.

Women tend to have smaller spleens than men, and taller people tend to have larger spleens than shorter people. In a study in the journal Radiology, researchers suggested that aside from men generally being taller than women, men also typically have greater red cell mass than women.

Your spleen, like the rest of your body, grows with age. Once you reach adulthood, however, your spleen tends to shrink slightly with each passing decade. The following is a list of the upper limit of normal spleen length by age up to 15 years. For boys and girls, there is relatively little difference in size, according to a study published in the American Journal of Roentgenology. The average spleen length by age was up to:

During a physical examination, your doctor can usually tell if your spleen is enlarged. A blood test to check your levels of red blood cells, white blood cells, and platelets may also be ordered to help diagnose the cause of a spleen enlargement.

Imaging tests, including ultrasound, help measure the size of your spleen and whether it’s crowding your other organs.

An abdominal ultrasound is often preferred for evaluating the spleen because it’s easy to do and doesn’t require any radiation. Ultrasound uses sound waves to create images of inside the body on a computer screen. An ultrasound “wand” is rubbed on the outside of the belly, which is coated with a special gel. This gel helps transmit the sound waves through the skin and to the parts inside the body.

Ultrasound can usually measure the length of the spleen along a center line (axis) accurately. It can also measure the width and thickness of the spleen, which can typically tell the doctor whether the organ is abnormally large or small. In most cases, however, the concern is about an enlarged spleen.

An abdominal ultrasound can help detect other conditions, too. Some of them include:

• abnormal liver function
• kidney stones
• gallstones
• enlargement of other organs, such as the liver or gallbladder
• abdominal aortic aneurysm (bulge in the main artery that supplies blood to most of the body)
• tumors or other suspicious growths anywhere in the abdominal area

Slight variances in spleen size are common and not a cause for concern. However, if you suspect your spleen is enlarged or you’re having any organ-related problems, see a doctor soon. If an infection is causing this temporary enlargement of the spleen, the sooner you get it diagnosed and treated, the better.

Treating the underlying cause of your spleen growth will usually cause it to return to a normal, healthy size. In very serious cases of spleen dysfunction, the organ can be removed. You will be at greater risk for infections, but that will only mean it’s even more important to keep up to date with vaccinations and other preventive steps, such as washing your hands thoroughly and regularly or avoiding people who may have a contagious infection.

Planning

Indication

Ultrasonography of the spleen is included as a general screening of the upper abdomen, or when specifically requested in the referral.

Evaluation

Size

Maximum length of spleen on abdominal ultrasonography.

A measurement of spleen size is a standard procedure as part of a liver exam, since splenomegaly is a sign of portal hypertension.

Suggested cutoffs are:^[1][2]

• Normal (not splenomegaly): the maximum length is less than 11 cm
• Moderate splenomegaly: the maximum length is between 11–20 cm
• Severe splenomegaly: the maximum length is greater than 20 cm

90% confidence intervals of maximum lengths in the normal population have lower limits between 6. 4 cm (in short women) and 10.2 cm (in tall men), and upper limits between 12.0 and 14.4 cm (respectively):^[3]

Age	Cutoff[4]
3 months	6. 0 cm
6 months	6.5 cm
12 months	7.0 cm
2 years	8.0 cm
4 years	9.0
6 years	9.5 cm
8 years	10.0 cm
10 years	11.0 cm
12 years	11.5 cm
15 years	12.0 cm for girls 13.0 cm for boys

For children, the cutoffs for splenomegaly are given in this table, when measuring the greatest length of the spleen between its dome and its tip, in the coronal plane through its hilum while breathing quietly.^[4]

Focal changes

If the referral mentions the spleen, it is generally appropriate to scan the volume of it for any focal changes, mainly cysts or tumors.

Report

• Even absence of enlargement. If enlarged, state both grade (such as moderate) and maximum length in a number
• If checked, even absence of focal changes.

dimensions, norm for ultrasound in adults and children, preparation for ultrasound

The spleen, despite its small size and auxiliary functions, is a very important organ. And although the removal of the spleen does not entail serious consequences, this organ is a faithful assistant in the formation of immunity, metabolism in the body, as well as in filtering blood from damaged corpuscles and foreign substances. Therefore, timely examination of the organ helps to prevent its loss, and possibly surgery.

Ultrasound of the spleen in adults and children

Ultrasound examination is based on the action of ultrasonic waves, which are completely harmless. The efficiency is somewhat lower compared to MRI, CT and others, but there are no restrictions. There are no contraindications to ultrasound for either children or adults. Ultrasound of the spleen can be done at all stages of pregnancy, infants from the first days of life and any patients during the entire disease several times, since ultrasound does not use any radiation technologies. How often you need to do an ultrasound of the spleen, the doctor decides. When it comes to ultrasound of the spleen, preparation for the procedure is devoid of special requirements.

Ultrasound of the spleen is an effective and, from a financial point of view, an affordable research method, therefore, if the spleen hurts, ultrasound can recognize the normal size in adults. Based on the deviations, the doctor will prescribe an effective treatment.

Indications for examination of the spleen

The main indication for ultrasound of the spleen is pain, which many diseases make themselves felt. If after the initial examination of the doctor the situation is not clarified, and the tests did not give a result, in most cases an ultrasound of the spleen is prescribed.

Ultrasound of the spleen is prescribed with a presumed increase in the organ in order to confirm or refute this, and also to find out the cause with a positive answer. In addition, diseases such as cirrhosis of the liver, leukemia, and infectious diseases are an absolute indication for ultrasound of the spleen. Ultrasound of the spleen may be prescribed to determine the location of metastases of a malignant tumor and with traumatic injuries of the abdominal cavity.

How to prepare for the procedure?

Preparation for ultrasound of the spleen is as follows: in 2-3 days, you will need to exclude from the diet foods that provoke gas formation, which can interfere with diagnosis. On each day of preparation, you must drink at least 1.5 liters of fluid, this will cleanse the digestive system. No food should be taken 5-6 hours before the procedure. Exception: pregnant women, infants and diabetics. If necessary, the doctor may prescribe drugs that improve the secretory function of the digestive system.

How is an ultrasound of the spleen done?

How should I prepare for an ultrasound of the spleen right in the office? To undergo an ultrasound in adults, you will need to lie on your back. The scanning sensor is moved from the costal arch to the end point of the organ. After the study in the supine position, the patient is turned on the right side, and the sensor is driven between the ribs until an image of the transverse sections of the spleen is obtained. If necessary, the patient may be told to lie on their stomach to continue the scan in the ribs. Since ultrasound of the spleen is a non-invasive research method, the patient does not experience any discomfort, except perhaps for the touch of a cold sensor.

Explanation of results

Directly during the ultrasound of the spleen, decoding is carried out by a specialist and further determines the course of the procedure. The specialist analyzes the position of the spleen relative to other organs: a healthy spleen is located on the left, at the top of the abdominal cavity, and the stomach is located in the middle of the spleen. During an ultrasound examination, it is important to pay attention to details: the diameter of the splenic vein of a healthy organ cannot be more than 1.5 cm, the echostructure of a healthy spleen must be homogeneous. Identified deviations are recorded in the conclusion. Subsequently, the doctor, based on the data obtained, makes a diagnosis and prescribes treatment.

Ultrasound norm of the spleen in adults

If the spleen is damaged, the size and norm in adults are determined by ultrasound in most cases, and other studies are not required. The norm of the spleen according to ultrasound in adults varies, depending on gender and individual characteristics of the body. The normal size of the spleen in men and women according to ultrasound is 8-14 cm in length, 3-5 cm in thickness and 5-7 cm in width. The mass of the spleen in women is 150-152 g, in men – 192-200 g.

Normal size of the spleen by ultrasound in children

How best to prepare a child for an ultrasound of the spleen, each parent decides for himself, since it is not recommended to move during the ultrasound. Indicators of the normal size of the spleen on ultrasound in children depend on age. In newborns, a healthy spleen does not exceed 4×3.8 cm in parameters, in children from 1 to 3 years old – 6.8×5 cm, from 3 to 7 years old – 8×6 cm, from 8 to 12 years old – 9×6 cm, from 12 to 15 years old – 10×6 cm. For children from 15 years old, sizes are considered normal, as in adults according to ultrasound.

What can ultrasound of the spleen show?

With the normal size of the spleen in adults and children, this organ “hides” behind the ribs. However, in case of abnormalities or pathologies, the spleen does not have normal sizes according to ultrasound and is visible from under the costal arch, shifting in the abdominal cavity. There are other symptoms that indicate damage and pathology of the spleen.

Gap

A sign of rupture during ultrasound of the spleen is fluid under the diaphragm or in the abdominal cavity, as well as uneven outlines of the organ. Rupture of the spleen occurs with aggressive mechanical action on it as a result of a blow or as a result of a disease, and it is possible to save the organ only in 1% of cases.

Hematoma

Hematoma or contusion of the spleen with untimely treatment can lead to rupture. Recognize hematoma by unevenly increased size, uneven outlines and bruising. Only ultrasound and other non-invasive research methods can see this damage.

Leukemic infiltration

Leukemic infiltration is a common injury to the spleen and liver in acute leukemia. Leukemic infiltration of the spleen is characterized not only by a change in its size, but also by an increase in echostructure, as well as a pointed edge and convex shapes. In the area of ​​​​the gates of the organ, lymph nodes increase.

Abscess

An abscess affects the spleen against the background of other diseases and is a purulent formation that threatens to rupture in the future. Abscess of the spleen is characterized by a hypoechoic or mixed echostructure, as well as the presence of a cyst. Requires immediate treatment.

Ultrasound of the spleen – is a method that uses an ultrasound signal to examine the spleen.

The spleen – is an organ that performs several important functions in the body. In the spleen, the formation of certain blood cells, as well as the renewal of some of them. In addition, the spleen is also part of the immune system.

Thus, a referral for an ultrasound examination of the spleen can be given by a hematologist (if a blood disease is suspected), a gastroenterologist, a therapist (if an increase in the size of this organ is detected), an allergist-immunologist (if a disease of the immune system is suspected), an infectious disease doctor (if some infectious diseases are suspected, for example: typhoid fever, mononucleosis, etc.).

What is the diagnostic value of ultrasound examination of the spleen?

Ultrasound can determine:

1. Size of the spleen (increase or decrease in the size of the organ).
2. Organ location
3. Fabric density
4. Presence or absence of pathological inclusions.
5. Spleen capsule integrity
6. Presence or absence of malignant neoplasms of the spleen.
7. Organ blood flow (examination of arteries and veins).
8. Presence or absence of infarction (areas of ischemia and necrosis) of the spleen.

Is it necessary to follow a diet before ultrasound of the spleen?

Due to the fact that the spleen is an organ located in the abdominal cavity, this examination should be performed on an empty stomach.

If the procedure is scheduled for the morning, then you can not take breakfast, and if the procedure is scheduled in the afternoon, the last meal should be no later than 6 hours before the ultrasound examination.

If a person is not on a diet, but is admitted to the hospital urgently and needs an ultrasound of the spleen, will they have this scan?

Of course, if there are indications (suspicion of rupture of the spleen capsule, suspicion of intra-abdominal bleeding), an ultrasound examination is mandatory, regardless of whether the patient took food before the examination or not.

How does the examination usually go?

For examination of the spleen, the patient is asked to remove outer clothing to the waist, lie on his back. Sometimes, for a more detailed examination, the patient may be asked to turn on their right side. This is necessary in order to increase the viewing angle of the left hypochondrium, just where the spleen is normally located.

What is the normal size of the spleen?

The normal dimensions of an organ are in the range: length from 11-12 cm, width 6-8 cm, thickness 4-5 cm (in an adult).

Where should the spleen normally be located?

The spleen is normally located in the region of the left hypochondrium between the 9th and 11th ribs. However, there may be pathological options: the spleen may be displaced, a person may have an additional smaller spleen (the so-called splenitis), in addition, in some very rare cases, the spleen may be completely absent (either as a variant of a congenital anomaly of development, or due to surgical removal of the organ in the patient’s history).

Why is such an indicator as the “density” of the spleen tissue examined?

In some diseases (for example: leukemia, mononucleosis), the density of the spleen tissue may be increased. It is for this reason that it is important to examine the density of the fabric in order to understand all the subtleties and nuances.

Why is the integrity of the spleen capsule examined?

Ultrasound can reveal rupture of the spleen capsule, bleeding from the vessels of the spleen, the presence of a hematoma under the capsule. As a rule, all these conditions are considered urgent and require emergency surgical care. It is for this reason that it is very important to correctly diagnose in time in order to save the patient’s life and prevent further blood loss and hemorrhagic shock.

Is it possible to determine the presence of a spleen tumor by ultrasound?

Yes, thanks to ultrasound diagnostics, tumor-like neoplasms in the spleen tissue (cysts, malignant tumors) can be seen. In addition, a significant diagnostic point is the determination of not only the tumor, its size, but also the presence of blood flow in the tumor tissue (how well the tumor is supplied with blood). To do this, dopplerometry of the vessels of the spleen is used, which makes it possible to assess the speed of blood flow and the presence of pathological vessels in this area.
