The Anatomy and Function of Cervical Lymph Nodes

Cervical lymph nodes are small, bean-shaped structures located throughout the neck region. These nodes play a crucial role in the body’s immune system, acting as filters for harmful pathogens and producing specialized white blood cells to combat infections. Understanding the anatomy and function of these lymph nodes is essential for recognizing and addressing potential health issues.

What are cervical lymph nodes?

Cervical lymph nodes are part of the larger lymphatic system, a network of tissues and organs that help fight infections and diseases. These nodes are responsible for filtering lymphatic fluid, also known as lymph, which flows through them. Normally, lymph nodes cannot be felt unless they are swollen, which can occur due to various reasons, including infections and, in rare cases, cancer.

Classification of cervical lymph nodes

Cervical lymph nodes are classified into two main groups:

• Superficial cervical lymph nodes: Located just beneath the skin
• Deep cervical lymph nodes: Situated deep within the neck

These groups are positioned around large vessels in the neck, such as the internal jugular vein and the internal carotid artery, as well as the spinal accessory nerve.

The Six Levels of Cervical Lymph Nodes

Healthcare professionals often refer to cervical lymph nodes using a level system, which helps in precise identification and diagnosis. There are six levels of cervical nodes, each with its own anatomic demarcation.

Level I: Submental and Submandibular Nodes

Level I lymph nodes are located along the lower border of the mandible. They drain the lower lip, mouth floor, tongue, and sublingual and submandibular glands.

Level II: Upper Jugular Group

These nodes are found along the upper third of the sternocleidomastoid muscle (SCM). They are divided into Level IIA and IIB based on their relation to the spinal accessory nerve. Level II nodes drain the posterior nasal cavity, oropharynx, hypopharynx, nasopharynx, and thyroid gland.

Level III: Middle Jugular Group

Located along the middle third of the SCM, Level III nodes drain the tonsil, soft palate, and posterior pharyngeal wall.

Level IV: Lower Jugular Group

These nodes are situated along the lower third of the SCM and are responsible for draining the supraglottic larynx, piriform sinus, and cervical esophagus.

Level V: Posterior Triangle Nodes

Also known as posterior triangle nodes, Level V lymph nodes are located in the posterior triangle of the neck. They include the spinal accessory nodes and drain the posterior scalp, posterior neck, and anterior chest wall.

Level VI: Anterior Cervical Lymph Nodes

Level VI nodes are located along the midline of the neck and include the pretracheal, paratracheal, prelaryngeal, and recurrent laryngeal nodes. They drain the thyroid gland, larynx, and trachea.

Common Causes of Cervical Lymphadenopathy

Cervical lymphadenopathy, or swelling of the cervical lymph nodes, can occur due to various reasons. Understanding these causes is crucial for proper diagnosis and treatment.

Viral and bacterial infections

The most common causes of cervical lymphadenopathy are viral and bacterial infections. These may include:

• Tonsillitis and adenoiditis
• Upper respiratory tract infections (URTI)
• Severe ear infections
• Other viral infections, such as mononucleosis or cytomegalovirus

Rare but serious causes

While less common, there are more serious conditions that can lead to swollen cervical lymph nodes:

• Tuberculosis
• Lymphoma
• Fungal infections
• Head and neck cancers with cervical lymph node involvement

Diagnosing Cervical Lymphadenopathy

When cervical lymph nodes become swollen, proper diagnosis is essential to determine the underlying cause and appropriate treatment.

Physical examination

A healthcare provider will typically begin with a thorough physical examination, palpating the neck area to assess the size, consistency, and tenderness of the lymph nodes. They may also check for other symptoms associated with the swelling.

Medical history

Taking a detailed medical history is crucial in diagnosing cervical lymphadenopathy. The healthcare provider will inquire about recent illnesses, travel history, and any other symptoms the patient may be experiencing.

Diagnostic tests

Depending on the initial findings, various diagnostic tests may be ordered:

• Blood tests: To check for infection markers or specific antibodies
• Imaging studies: Such as ultrasound, CT scan, or MRI to visualize the affected lymph nodes and surrounding structures
• Fine-needle aspiration (FNA): A minimally invasive procedure to obtain a sample of cells from the swollen lymph node for further analysis
• Biopsy: In some cases, a larger tissue sample may be necessary for a definitive diagnosis

Treatment Options for Cervical Lymphadenopathy

The treatment of cervical lymphadenopathy depends on the underlying cause. Here are some common approaches:

Addressing infections

For bacterial infections, antibiotics may be prescribed. Viral infections often resolve on their own, but supportive care may be recommended to manage symptoms.

Managing inflammation

Over-the-counter pain relievers and anti-inflammatory medications can help reduce discomfort and swelling associated with cervical lymphadenopathy.

Treating underlying conditions

If the swollen lymph nodes are due to a more serious condition such as lymphoma or tuberculosis, specific treatments tailored to these diseases will be necessary.

Surgical intervention

In rare cases, surgical removal of the affected lymph nodes may be required, particularly if cancer is suspected or if the swelling does not resolve with other treatments.

Prevention Strategies for Cervical Lymph Node Swelling

While it’s not always possible to prevent cervical lymphadenopathy, there are steps you can take to reduce your risk:

Maintain good hygiene

Practicing good personal hygiene, such as regular handwashing and avoiding close contact with sick individuals, can help prevent infections that may lead to swollen lymph nodes.

Boost your immune system

A healthy lifestyle that includes a balanced diet, regular exercise, adequate sleep, and stress management can help strengthen your immune system, making you less susceptible to infections.

Stay up-to-date on vaccinations

Keeping your vaccinations current can protect you from various infections that might cause cervical lymphadenopathy.

Regular health check-ups

Routine medical examinations can help detect and address potential health issues before they lead to complications, including swollen lymph nodes.

When to Seek Medical Attention for Swollen Cervical Lymph Nodes

While swollen cervical lymph nodes are often harmless and resolve on their own, there are situations where medical attention is necessary.

Persistent swelling

If the swelling in your cervical lymph nodes persists for more than two weeks without any signs of improvement, it’s advisable to consult a healthcare provider.

Accompanying symptoms

Seek medical attention if you experience any of the following symptoms along with swollen cervical lymph nodes:

• Unexplained weight loss
• Night sweats
• Persistent fever
• Difficulty swallowing or breathing
• Redness or warmth of the skin over the swollen lymph nodes

Rapid growth or hardening of lymph nodes

If you notice that the swollen lymph nodes are growing rapidly or becoming hard and fixed in place, it’s important to have them evaluated by a healthcare professional promptly.

Understanding cervical lymph nodes and being aware of the signs and symptoms associated with their swelling can help you make informed decisions about your health. While cervical lymphadenopathy is often benign, it’s essential to seek medical attention when necessary to ensure proper diagnosis and treatment. By following prevention strategies and maintaining good overall health, you can reduce your risk of experiencing swollen cervical lymph nodes and support your body’s immune function.

Swollen Cervical Lymph Nodes 101: Anatomy, Causes, Treatment​

Cervical lymph nodes are small, bean-shaped structures located throughout the neck. These are an essential part of the immune system and play a crucial role in filtering and destroying harmful pathogens. However, when these enlarge and become swollen lymph nodes, it could indicate the presence of an an underlying medical condition known as cervical lymphadenopathy. In this article, we will explore the various aspects of swollen cervical lymph nodes and cervical lymphadenopathy, including their functions, causes, symptoms, diagnosis, treatment, and prevention.

What Are Cervical Lymph Nodes?

Cervical lymph nodes are a part of the lymphatic system, a network of tissues and organs that help fight infections and diseases. These nodes are located in the neck and are responsible for filtering the lymphatic fluid, also known as lymph, that flows through them. Lymph nodes are scattered throughout the body. They are part of the body’s immune system. These nodes help fight infection by producing special white blood cells. They also work by trapping bacteria, viruses, and cancer cells. Normally, lymph nodes cannot be felt unless they are swollen. Infection, usually by a virus, is the most common cause of swollen lymph nodes; other causes of swollen cervical lymph nodes include bacterial infection and cancer.

Cervical lymph nodes specifically refer to lymph nodes in the region of the head and neck, and are divided into two main groups, the superficial cervical lymph nodes located just beneath the skin, and the deep cervical lymph nodes located deep within the neck. These groups are located around large vessels in the neck, namely the  internal jugular vein and the internal carotid artery; and an important nerve – the spinal accessory nerve. There are other groups of lymph nodes, such as axillary lymph nodes and inguinal lymph nodes, which are located in in the armpit and groin region respectively.

You may also come across the location of  cervical nodes being described as being at different levels. These neck node levels are the same as described above, but are mainly used by healthcare professionals, and will be listed here as well for completeness.

What Are The Cervical Lymph Nodes Levels?

There are six levels of cervical nodes, each with their own anatomic demarcation. These levels are numbered I to VI, from the most superficial (closest to the skin’s surface) to the deepest (closest to the spine).

Level I Lymph Nodes

Level I lymph nodes are located along the lower border of the mandible and include the submental and submandibular lymph nodes. These nodes drain the lower lip, mouth floor, tongue, sublingual and submandibular glands.

Level II Lymph Nodes

Level II lymph nodes are located along the upper third of the sternocleidomastoid muscle (SCM) and include the upper jugular group. They are split into Level IIA and IIB by the location of the spinal accessory nerve. These nodes drain the posterior nasal cavity, oropharynx, hypopharynx, nasopharynx, and thyroid gland.

Level III Lymph Nodes

Level III lymph nodes are located along the middle third of the SCM and include the middle jugular group. These nodes drain the tonsil, soft palate, and posterior pharyngeal wall.

Level IV Lymph Nodes

Level IV lymph nodes are located along the lower third of the SCM and include the lower jugular group. These nodes drain the supraglottic larynx, piriform sinus, and cervical esophagus.

Level V Lymph Nodes

Level V lymph nodes are also known as posterior triangle nodes. They are located in the posterior triangle of the neck and include the spinal accessory nodes (which are in close relation to the spinal accessory nerve). These nodes drain the posterior scalp, posterior neck, and anterior chest wall.

Level VI Lymph Nodes

Level VI lymph nodes are also known as anterior cervical lymph nodes, and are located along the midline of the neck. They include the pretracheal, paratracheal, prelaryngeal and recurrent laryngeal nodes. These nodes drain the thyroid gland, larynx, and trachea.

Understanding the levels of cervical lymph nodes and their anatomic demarcation is important for healthcare professionals when evaluating patients with cervical lymphadenopathy, as it can help determine the potential cause of lymph node enlargement and the appropriate treatment options.

Causes Of Cervical Lymphadenopathy

Causes of cervical lymphadenopathy are usually viral or bacterial infection, which can include:

• Infection of the tonsils and adenoids
• Upper respiratory tract infections (URTI)
• Severe ear infection
• Other viral infections

There are also other more serious infections that can cause swollen cervical lymph nodes. Fortunately, these are rare, and include:

• Tuberculosis
• Lymphoma
• Fungal Infections
• Head and Neck Cancers with cervical lymph node metastasis
  • Cancers of the thyroid gland
  • Squamous cell carcinoma of the head and neck region

Symptoms Of Swollen Cervical Lymph Nodes

The most noticeable symptom of swollen lymph nodes is the enlargement of the cervical lymph nodes. The enlarged nodes can be felt as small, hard, and painless lumps beneath the skin. They may be painless swelling, or they may be painful. Depending on the underlying cause, cervical lymphadenopathy can also present with other symptoms such as:

• Fever
• Fatigue
• Night sweats
• Weight loss
• Sore throat
• Skin rashes
• Joint pain

Diagnosis Of Cervical Lymphadenopathy

To diagnose a swollen cervical lymph node, a medical history, as well as as a physical examination will be performed. The location, size, and texture of the enlarged lymph nodes will then be determined. Additional tests such as blood tests, imaging tests, and a biopsy may be performed to determine the underlying cause of the lymph node enlargement.

How Are Swollen Cervical Lymph Nodes Investigated?

Flexible Nasoendoscopy

In the majority of cases of swollen lymph nodes with no obvious cause, flexible nasoendoscopy is performed. This involves the insertion of a small, thin tube into the nostrils to assess the nasal cavity and throat for the presence of lesions which may be related to cervical lymphadenopathy.

Imaging

Imaging is frequently requested in order to asses the site and extent of cervical lymph node swelling. Imaging may also pick up other abnormalities which may be causing or are related to cervical lymphadenopathy. This may take the form of ultrasound examinations, computed tomography (CAT) scans, or Magnetic resonance imaging (MRI) scans.

Blood Tests

Routine blood tests are run to look for a high white blood count that would suggest a bacterial infection. Other more specific blood tests may be run if other conditions are suspected.

Biopsy

Lymph nodes can be biopsied in the following ways:

Fine needle aspiration (FNA)

A thin needle with a hollow tube is inserted into the lesion to remove fluid and sample cells for testing. A fine-needle aspiration is usually completed within 10-15 minutes, and there is little to no patient down time. This is usually the first type of biopsy performed.

Core needle biopsy

This biopsy is similar to a fine needle aspiration, except a larger needle is used. With the larger hollow center, a small block of tissue can be removed for testing, allowing more information to be collected than with fluid or cells. Local anesthesia is typically utilized, and the procedure lasts approximately 15-30 minutes.

Open biopsy

A small incision is made in order to remove part or all of the cervical lymph node. The procedure is most often performed with local anesthesia applied to the biopsy site, but general anesthesia may also be used in cases where it is desirable for the patient to be sleeping. An open biopsy usually takes less than an hour, and afterward, your surgeon will close the site with sutures and apply a bandage. The incision takes approximately 10-14 days to heal, during which strenuous activity should be avoided. Open biopsies are only performed if FNA biopsy or core needle biopsies are inconclusive; or if the patient’s medical condition necessitates it.

How Is Cervical Lymphadenopathy Treated?

Cervical lymphadenopathy should be investigated and treated if it has been present for a prolonged duration, or if there is any concern about an underlying malignancy. In cases where the lymph node enlargement is due to an infection, antibiotics or antiviral medications may be prescribed. In cases where the lymph node enlargement is due to an inflammatory condition, corticosteroids or other immunosuppressive medications may be used to reduce inflammation. In cases where the lymph node enlargement is due to cancer, treatment may involve neck surgery, chemotherapy, radiation therapy, or a combination of these treatments.

Conclusion

Cervical lymphadenopathy is a condition where the cervical lymph nodes become enlarged due to an underlying medical condition. While it is not a disease in itself, it can indicate a range of medical conditions, including infections, inflammatory conditions, and cancer. The symptoms include swollen lymph nodes, fever, fatigue, and weight loss. The treatment of these swollen nodes depends on the underlying cause, and prevention involves taking measures to prevent these.

If you notice any unusual lumps or bumps in the neck, it is important to seek medical attention promptly.

What Causes Neck Lymph Node Pain?

Lymph node pain in the neck can adversely impact your routine life. It’s usually a result of a bacterial or viral infection which can cause a swollen lymph node in the neck. In rare cases, swollen lymph nodes in the neck that cause you pain and discomfort might be a sign of cancer.

So what causes neck lymph node pain? Your lymph nodes (also known as lymph glands) are your body’s natural filter mechanism that traps bacteria and viruses before they can cause infections in your body. When antigens are present in your system, your lymphatic system responds to the inflammatory conditions with swollen lymph nodes, which can cause you to experience neck pain.

Causes of Lymph Node Pain in the Neck

Swollen lymph nodes along your neck can put you in a great deal of pain. These can be due to a number of infectious diseases (usually bacterial or viral) such as a viral throat infection. They can also be the result of non-infectious causes. These swollen lymph nodes along the neck come under a medical condition called lymphadenopathy. Alternatively, the condition is known as lymphadenitis if there’s an acute inflammation and swollen gland around these lymph nodes.

Acute infectious causes of swollen lymph nodes include adenovirus, enterovirus, influenza virus, streptococcus, and other pathogens. On the other hand, chronic infectious causes of lymphadenitis include EBV, HIV, and tuberculosis. Non-infectious inflammatory conditions caused by Kawasaki disease and Hodgkin lymphoma. can also lead to lymph node pain in the neck. Here are some of the most prevalent causes of swollen lymph nodes and neck pain:

Skin Abscess

An infective cause of lymph node pain in the neck may be the formation of abscesses or similar skin infections. A skin abscess is a sizable pus pocket that has developed immediately below the skin. It is brought on by bacteria that enter the skin through a minor cut and starts to grow there. White blood cells help the body combat the invasion by killing some diseased tissue while forming pus in the cavity that is left behind.

These abscesses are often accompanied by swollen lymph nodes, acute pain in the neck, fever, and body chills. For minor cases, the body’s immune system will take care of healing the abscess, but in some cases, the intake of antibiotics may be recommended by the doctor to prevent complications. A retropharyngeal abscess is a rare and life-threatening complication that may require urgent medical attention depending on the severity of neck pain.

Fibromyalgia

Fibromyalgia is a condition that can cause lymph node pain in the neck, fatigue, tenderness of the skin, musculoskeletal pain, and even depression. Traumatic events such as a divorce, car accident, or mental stress may lead to fibromyalgia. If it’s genetically driven, the patient may experience neck pain and develop swollen lymph nodes even for normal touches. This pain is often accompanied by cloudy thoughts, severe headaches, and increased sensitivity to stimuli.

The goal of treatment is to reduce the inflammation of swollen lymph nodes and symptoms. Treatment solutions will aim to enhance the patient’s quality of life through painkillers, exercise, a better diet, and support for dealing with stressful situations. Patients who have neck pain and swollen lymph nodes due to fibromyalgia need to consult with their primary care doctor at the earliest.

Thyroiditis

Acute thyroiditis is a rare medical condition that can cause inflammation of the thyroid gland. This is usually due to radiation, trauma, infection, or a side-effect of medication. Patients with acute thyroiditis will experience sharp pain in front of the neck accompanied by swelling of normal nodes that are part of your lymphatic system. Having a sore throat, hoarse voice, fever, and feeling of being severely ill are common symptoms of this disease.

You should visit an ER right away as this may be a medical emergency. The doctors will diagnose your condition using thyroid function testing, blood tests, and imaging. Common treatment solutions for swollen lymph glands due to thyroiditis include antibiotics, stopping causative drugs, and supportive care.

Lymph Node Inflammation

When there’s an increased presence of inflammatory cells in the neck region, the lymph gland tends to swell and enlarge. An enlarged lymph node in the neck is usually a sign of an infection detected by your lymphatic system. Sometimes, this inflammation may occur for no apparent reason.

You may observe visible lumps and bumps on your neck that might be causing you pain. Fever and weight loss are common symptoms associated with lymph node inflammation. If you think your lymph nodes should be examined, talk to your doctor about it. Use a warm, wet compress on the region to be treated to hasten the healing process.

Myofascial Pain Syndrome

Myofascial pain syndrome (also known as chronic myofascial pain) is a common cause for neck pain around the lymph nodes. This condition can cause you to feel pain at a different part of your body when pressure is applied to certain muscles in your body. Myofascial pain is usually a result of overuse of muscle, muscular injury, poor posture, tension, or stress which can lead to a habitual tightening of the affected muscles.

The scar tissues in the overused muscles are known as trigger points as they can trigger pain when stimulated. Pain that worsens over time and the inability to sleep are common symptoms of myofascial pain. You need to consult with your medical provider at the earliest as the myofascial pain syndrome can develop into fibromyalgia.

Symptoms Associated with Neck Lymph Node Pain

The baseline symptom of having lymph node pain in the neck region is swollen nodes that are the size of kidney beans and are tender to touch. Depending on the cause of your neck pain in the lymphatic system, other symptoms include:

• Sensitivity and pain in the lymphatic nodes
• Swelling in and around the neck
• Symptoms of an upper respiratory disease such as sore throat, fever, hoarse voice, and runny nose
• Indicators of infection or immune system disorder
• Indicators of a cancerous lymphoma
• Insomnia
• Night sweats

Swollen lymph nodes that cause neck pain usually return to normal when the infection subsides. You may need to consult a doctor if the lymph node inflammation has appeared for no apparent reason, has a hard consistency when you touch them, and continues to enlarge beyond 4 weeks.

Treatment Options for Neck Lymph Node Pain

Treatment options recommended for neck pain due to swelling of lymph nodes usually depend on the specific cause. A healthcare provider may recommend the following set of treatment solutions in case of intensive swelling in the neck:

• Antibiotics: Antibiotics are given when an underlying bacterial infection is the cause of lymph node pain in the neck.
• Supportive care: If the cause of the lymph node inflammation is viral, then antibiotics won’t have any effect, and you may be given supportive care. Apart from resting and pain medication, your doctor may also recommend specific treatments for diseases such as HIV.
• Warm compress: Applying a warm and wet compress using a soft cloth dipped in hot water on the neck can provide great pain relief.
• Pain relievers: Over-the-counter painkillers are a great way to manage pain while the infection passes. Aspirin, Advil, Motrin, Aleve, and Tylenol are the most common ones. Always consult with your doctor before taking these pain killers.
• Cancer treatment: Swollen glands and enlarged lymph nodes may be indicative of cancer. Cancer treatment for lymphomas usually involves several rounds of immunotherapy medications, chemotherapy, and radiation therapy. In the worst of cases, you may even require a bone marrow transplant.

Preventive Measures for Lymph Node Pain in the Neck

There are a number of preventive measures you can take to avoid getting an infection and stop the symptoms of lymphatic inflammation. Here are some of the most proven preventive care strategies that medical professionals recommend for patients at risk of getting neck pain due to a lymph node inflammation:

• Observing proper sanitation practices such as regular use of soap and water to wash hands
• Using your elbow instead of using your hands to cover your coughs and sneezes
• Avoiding contact with people who are sick
• Avoiding touching your face with unwashed hands
• Disinfecting flat surfaces at your house
• Maintaining a healthy sleep cycle

Inflammation of the lymph nodes in cats – symptoms and treatment of lymphadenitis in cats in Moscow. Veterinary clinic “Zoostatus”

Signs
Diagnosis
Treatment

Lymphadenitis is an inflammation of the lymph nodes.

Lymph nodes act as “filters” that protect the body from the spread of foreign agents: all lymph passes through the lymph nodes before entering the bloodstream. They contain immune cells that, if necessary, form an immune response. Inflammation of the lymph nodes is not an independent disease, but a symptom indicating the presence of inflammation in the body. The lymph nodes closest to the focus of inflammation are the first to be affected.

Signs

An inflamed lymph node increases in size, swells, may be painful, the skin over it may turn red, the lymph nodes themselves feel smooth to the touch. With inflammation of the submandibular lymph nodes in a cat, eating is difficult, and breathing problems may occur. With inflammation of the axillary or inguinal lymph nodes, lameness may occur.

Cats with lymphadenitis often have fever, lethargy, and loss of appetite.

Enlargement of superficial lymph nodes can be easily noticed by an attentive owner by simply stroking and feeling the cat. If an increase in one or more lymph nodes is detected (even if the animal feels otherwise well), it is necessary to take the cat to the veterinarian as soon as possible!

It is not necessary to delay the visit to the doctor, in this case there is a risk of developing pathologies dangerous to health and life. Click on the phone number and call our veterinary center right now

8 (499) 372 00 57
Or you can request a call back.

Diagnosis

If lymphadenitis is suspected, a thorough history taking, examination with palpation of all superficial lymph nodes, general and biochemical blood tests are carried out.

Sometimes additional diagnostic tests are required: abdominal ultrasound, radiography, lymph node biopsy, bacteriological, virological or mycological examination.

Treatment

Treatment should be directed at the cause of the lymphadenitis. So, with inflammation of the submandibular lymph nodes, treatment of diseases of the oral cavity (gingivitis, stomatitis, abscesses, diseased teeth) is usually required.

If a systemic infection is detected, antibiotics and antifungal drugs are prescribed.

Purulent inflammation of the lymph node may require surgical treatment: opening and drainage of the abscess.
