What Are Ganglion Cysts and How Do They Form?

Ganglion cysts are non-cancerous, fluid-filled lumps that commonly develop near joints or tendons in the hand, wrist, and foot. These soft, gel-like masses often change in size and are typically smooth and round in appearance. They form when synovial fluid leaks out of a joint or tendon tunnel, creating a swelling beneath the skin.

While the exact cause of ganglion cysts is often unknown, they may result from:

• Trauma to the affected area
• Underlying arthritis
• Repetitive stress on the joint or tendon

Ganglion cysts are the most common type of hand and wrist swelling, accounting for approximately 60-70% of all soft tissue tumors in these areas. They are generally harmless and can often be left untreated without causing significant issues.

Who Is Most Likely to Develop Ganglion Cysts?

Ganglion cysts can affect people of all ages, but certain demographic groups are more prone to developing them:

• Women are three times more likely than men to develop ganglion cysts
• Most commonly occurs in individuals between 20 and 40 years of age
• Gymnasts and other athletes who repeatedly stress their wrists may be at higher risk

Do certain occupations increase the risk of developing ganglion cysts? While no specific occupation has been definitively linked to an increased risk, jobs that involve repetitive hand and wrist movements or place excessive stress on these joints may potentially contribute to their formation.

Common Locations and Types of Ganglion Cysts

Ganglion cysts can develop in various locations, but some areas are more common than others. Understanding the different types can help in identifying and managing these cysts:

Wrist Ganglion Cysts

Approximately 80% of ganglion cysts are found in the wrist area. They can be categorized into two main types:

1. Dorsal Wrist Ganglions: These occur on the back of the wrist and are most common in young adults. They often disappear without treatment.
2. Volar Wrist Ganglions: Found on the front of the wrist, these can affect young adults but are also seen in older individuals with arthritis.

Hand and Finger Ganglion Cysts

Ganglion cysts can also appear on the hands and fingers:

• Flexor Tendon Sheath Ganglions: These develop at the base of the finger, typically in young adults.
• Mucoid Cysts: Usually occurring in middle-aged or older people, these cysts form on the fingers, often near the nail bed.

Can ganglion cysts develop in other parts of the body? While less common, ganglion cysts can also form in other areas such as the ankle, foot, and knee.

Recognizing the Symptoms of Ganglion Cysts

Ganglion cysts can present with various symptoms, although some may be asymptomatic. Common signs and symptoms include:

• A visible lump or swelling, which may change in size over time
• Pain or discomfort, especially when the affected joint is in use
• Limited range of motion in the affected joint
• A tingling sensation or numbness if the cyst presses on nearby nerves
• Weakness in the affected area

Is pain always present with ganglion cysts? Not necessarily. Many ganglion cysts are painless and only cause concern due to their appearance or size. However, pain can occur if the cyst presses on a nerve or interferes with joint movement.

Diagnosing Ganglion Cysts: What to Expect

The diagnosis of ganglion cysts is typically straightforward and involves the following steps:

1. Physical Examination: A healthcare professional will visually inspect and palpate the affected area to assess the size, shape, and consistency of the lump.
2. Medical History: Your doctor will ask about your symptoms, how long you’ve had the lump, and any changes you’ve noticed.
3. Transillumination: This simple test involves shining a light through the cyst to determine if it’s filled with fluid.
4. Imaging Studies: In some cases, additional tests may be necessary:
   • X-rays: To rule out bone abnormalities or arthritis
   • Ultrasound: To confirm the cyst is fluid-filled and not a solid mass
   • MRI: For more detailed imaging, especially if the diagnosis is uncertain

How accurate is the diagnosis of ganglion cysts? While physical examination and patient history are often sufficient for diagnosis, imaging studies can provide a definitive diagnosis with high accuracy, particularly in cases where the presentation is atypical.

Treatment Options for Ganglion Cysts

The treatment approach for ganglion cysts depends on various factors, including the size of the cyst, its location, and the presence of symptoms. Here are the main treatment options:

1. Observation

About 50% of ganglion cysts disappear on their own without any intervention. For this reason, a “wait and see” approach is often recommended, especially in the early stages or for asymptomatic cysts.

2. Non-Surgical Treatments

• Immobilization: Wearing a wrist brace or splint can help reduce pain and may cause the cyst to shrink.
• Aspiration: This involves draining the fluid from the cyst using a needle. While it can provide immediate relief, the cyst often returns.
• Medications: Over-the-counter pain relievers can help manage discomfort associated with ganglion cysts.

3. Surgical Removal

Surgery may be considered if the cyst causes significant pain, interferes with joint function, or hasn’t responded to other treatments. The procedure involves removing the cyst along with part of the involved joint capsule or tendon sheath.

What is the success rate of ganglion cyst surgery? While surgery is generally effective, there is a recurrence rate of about 10-40%, depending on the location of the cyst. Dorsal wrist ganglions have a lower recurrence rate (about 10%) compared to volar wrist ganglions (30-40%).

Potential Complications and Risks

While ganglion cysts are generally harmless, certain complications can arise, especially following treatment:

• Recurrence: Ganglion cysts can return, even after surgical removal.
• Infection: Particularly following aspiration or surgery, though this is rare.
• Nerve damage: In some cases, nearby nerves may be affected during treatment, leading to numbness or altered sensation.
• Stiffness: Post-surgical stiffness in the affected joint can occur but usually resolves with physical therapy.
• Scarring: Surgical removal may leave a small scar.

Are there any long-term health risks associated with untreated ganglion cysts? In most cases, untreated ganglion cysts do not pose significant long-term health risks. However, if they press on nerves or interfere with joint movement, they could potentially lead to chronic pain or reduced mobility if left untreated for extended periods.

Living with Ganglion Cysts: Practical Advice and Management

If you have been diagnosed with a ganglion cyst, here are some practical tips to help you manage your condition:

1. Monitor the cyst: Keep track of any changes in size, appearance, or associated symptoms.
2. Avoid self-treatment: Refrain from attempting to “pop” or drain the cyst yourself, as this can lead to infection.
3. Use protective padding: If the cyst is in an area prone to bumps or pressure, consider using padding to protect it.
4. Modify activities: If certain activities exacerbate your symptoms, try to modify or avoid them when possible.
5. Apply ice: Cold therapy can help reduce pain and inflammation associated with ganglion cysts.
6. Practice gentle exercises: Gentle range-of-motion exercises can help maintain joint flexibility.
7. Maintain a healthy lifestyle: A balanced diet and regular exercise can support overall joint health.

How can you prevent ganglion cysts from recurring? While there’s no guaranteed way to prevent ganglion cysts, maintaining good joint health through proper ergonomics, avoiding repetitive stress, and promptly addressing any joint injuries may help reduce the risk of recurrence.

When to Seek Medical Attention for a Ganglion Cyst

While many ganglion cysts don’t require immediate medical attention, there are circumstances where you should consult a healthcare professional:

• The cyst is painful or interferes with joint movement
• The cyst is growing rapidly or has reached a large size
• You notice changes in skin color or texture over the cyst
• The cyst is causing numbness or tingling in the affected area
• You’re unsure if the lump is a ganglion cyst or another type of growth
• The cyst returns after previous treatment

Can ganglion cysts become cancerous? Ganglion cysts are benign (non-cancerous) and do not have the potential to become malignant. However, it’s always best to have any new or changing lumps evaluated by a healthcare professional to ensure an accurate diagnosis.

Future Outlook and Ongoing Research

As medical understanding of ganglion cysts continues to evolve, researchers are exploring new treatment options and investigating the underlying causes of these common soft tissue lumps. Some areas of ongoing research include:

• Improved imaging techniques for more accurate diagnosis
• Development of non-invasive treatments to reduce recurrence rates
• Investigation into genetic factors that may predispose individuals to ganglion cysts
• Exploration of the relationship between joint biomechanics and cyst formation
• Studies on the effectiveness of various conservative treatments

What new treatments for ganglion cysts are on the horizon? While current treatments are generally effective, researchers are exploring minimally invasive techniques such as ultrasound-guided treatments and novel pharmacological approaches to prevent cyst formation or reduce recurrence rates. However, these are still in the experimental stages and require further study before becoming widely available.

In conclusion, while ganglion cysts can be bothersome, they are generally harmless and often resolve on their own. Understanding the nature of these cysts, recognizing their symptoms, and knowing when to seek medical attention can help individuals manage this common condition effectively. As research continues, we may see new and improved treatment options emerge, offering better outcomes for those affected by ganglion cysts.

Ganglion cyst | NHS inform

Ganglion cysts are soft, gel-like masses that often change size.

They tend to be smooth and round, and are:

• the most common type of swelling in the hand, wrist and foot
• harmless and can safely be left alone

If you have a ganglion, try to stay positive. There’s a lot you can do to help yourself.

What causes ganglion cysts?

A ganglion cyst starts when the fluid leaks out of a joint or tendon tunnel and forms a swelling beneath the skin.

The cause of the leak is generally unknown, but may be due to trauma or underlying arthritis.

How common are they?

Ganglion cysts are 3 times more common in women than men between 20 and 40 years of age.

Types of ganglion cysts

Ganglions can form:

• at the back of the wrist – these typically occur in young adults and often disappears without treatment
• at the front of the wrist – these may occur in young adults, but also seen in older people with arthritis
• at the base of the finger (flexor tendon sheath) – these usually occur in young adults
• on the finger (mucoid cyst) – these usually occur in middle-aged or older people

Approximately 80% of ganglions are found in the wrist.

Ganglion cyst symptoms

If you have a ganglion cyst the swelling can become noticeable, but often there are no symptoms at all.

Sometimes a ganglion can cause pain and limit movement in your joint. Some people are also concerned about the cysts appearance.

Most symptoms settle with time.

How they’re diagnosed

To diagnose a ganglion cyst, a healthcare professional will ask you about it and examine your wrist and hand.

Giving a diagnosis is usually straightforward. However, scans may be helpful if the diagnosis is uncertain.

Treating a ganglion cyst

About 50% of ganglions disappear on their own without treatment. In the early stages you should wait to see if this happens.

You won’t need treatment unless the cyst is painful.

Medication

Many people take medication to cope with their pain and symptoms, and help them remain active.

You may be prescribed pain medication to ease the pain. Make sure you take any medication as prescribed, and get advice from a GP, pharmacist or suitably trained healthcare professional.

Surgery

If the ganglion hasn’t reduced in size after 6 months or is causing significant functional difficulty and/or pain, you may be referred for further help and possible surgery.

Surgery is considered if it causes significant pain or restricts movement in your joint. However, there’s a chance it will come back even after surgery.

Ganglion cyst at the back of the wrist

Draining this ganglion can reduce the swelling but it often returns.

Problems after surgery include:

• persistent pain
• loss of wrist movement
• painful trapping of nerve branches in the scar

There’s a 10% chance of it coming back again after surgery.

Ganglion cyst at the front of the wrist

Draining this ganglion may be useful, but it can be dangerous as the cyst is often close to the artery at the wrist (where you can feel the pulse).

Problems after surgery include:

• persistent pain
• loss of wrist movement
• trapping of nerve branches in the scar

For these reasons, many surgeons advise against operating on these cysts.

There’s a 30 to 40% chance of it coming back again after surgery.

Ganglion cyst at the base of the finger

These ganglions feel like a dried pea at the base of the finger, and can cause pain when gripping.

Problems after surgery include:

• persistent pain
• loss of finger movement
• painful trapping of nerve branches in the scar

There’s a small chance of it coming back again after surgery.

Finger ganglion cyst

These ganglions are associated with wearing out of the end joint of a finger. Pressure from the cyst may cause a furrow in the fingernail. Occasionally the cyst fluid leaks through the thin overlying skin.

Problems after surgery include:

• infection
• stiffness and pain from the worn out joint

There’s a 10% chance of it coming back again after surgery.

Work

If you have a ganglion cyst try to stay at or get back to work as soon as possible. You don’t need to be fully pain and symptom free to return to work.

Research shows the longer you’re off work the less likely you are to return.

Ganglion Cyst of the Wrist and Hand – OrthoInfo

Ganglion cysts are the most common mass or lump in the hand. They are not cancerous and, in most cases, are harmless. They occur in many locations, but most often develop on the back of the wrist.

These fluid-filled cysts can quickly appear, disappear, and change size. Many ganglion cysts do not require treatment. However, if the cyst hurts, if it affects function, or if you are unhappy with how it looks, there are several treatment options available.

A ganglion arises out of a joint, like a balloon on a stalk. It grows out of the tissues surrounding a joint, such as ligaments, tendon sheaths, and joint linings. Inside the balloon is a thick, slippery fluid, similar to the fluid that lubricates your joints.

The most common location of a ganglion cyst is on the back of the wrist.

Ganglion cysts can develop in several of the joints in the hand and wrist, including:

• Both the top and underside of the wrist
• The end joint of a finger
• The base of a finger

They vary in size, and in many cases, grow larger with increased activity. With rest, the lump usually becomes smaller.

It is not known what triggers the formation of a ganglion.

• They are most common in younger people between the ages of 15 and 40
• Women are more likely to be affected than men.
• They are common among gymnasts, who repeatedly apply stress to the wrist.
• Ganglion cysts that develop at the end joint on the nail side of a finger — also known as mucous cysts — are typically associated with arthritis in the finger joint and are more common in women between the ages of 40 and 70.

A mucous cyst at the end of the index finger.

Most ganglions form a visible lump; however, smaller ganglions can remain hidden under the skin (occult ganglions). Although many ganglions produce no other symptoms besides the appearance of a mass, if a cyst puts pressure on the nerves that pass across the joint, it can cause pain, tingling, and muscle weakness.

If you have a large cyst, even if it is not painful, you may feel anxious or unhappy simply because of how it looks.

Medical History and Physical Examination

During the initial appointment, your doctor will discuss your medical history and symptoms. They may ask you:

• How long you have had the ganglion
• Whether it changes in size
• Whether it is painful

Your doctor may apply pressure to the cyst to test for tenderness or discomfort. Because a ganglion is filled with fluid, it is translucent (almost transparent). Your doctor may shine a penlight up to the cyst to see whether light shines through. This can help confirm that the mass is truly a cyst and not a solid tumor.

Imaging Tests

X-rays. X-rays create clear pictures of dense structures, like bone. Although X-rays will not show a ganglion cyst, they can be used to rule out other conditions, such as arthritis of the hand, arthritis of the wrist, or a bone tumor.

Magnetic resonance imaging (MRI) scans or ultrasounds. MRI scans and ultrasounds can better show soft tissues, like a ganglion, than X-rays. Sometimes, an MRI or ultrasound is needed to find an occult ganglion that is not visible, or to distinguish the cyst from other tumors. However, further imaging is often not needed prior to treatment. 

Nonsurgical Treatment

Initial treatment of a ganglion cyst is nonsurgical.

Observation. If you have no pain or other symptoms, your doctor may recommend just waiting and watching to make sure that no unusual changes occur. This is typically safe because ganglions are not cancerous and may disappear on their own in time.

Immobilization. Activity often causes the ganglion to increase in size, which may increase pressure on surrounding nerves, causing pain. A wrist brace or splint may relieve symptoms and cause the ganglion to decrease in size. As pain decreases, your doctor may prescribe exercises to strengthen the wrist and improve range of motion.

Aspiration. If the ganglion causes a great deal of pain or severely limits activities, the fluid may be drained from it.  This procedure is called an aspiration.

The area around the ganglion cyst is numbed and the cyst is punctured with a needle so that the fluid can be withdrawn.

Unfortunately, aspiration often fails to eliminate the ganglion because the root or connection to the joint or tendon sheath is not removed. A ganglion can be like a weed which will grow back if the root is not addressed. Thus, in many cases, the ganglion cyst returns after an aspiration procedure.

Aspirations are most often used for ganglions located on the top of the wrist. Ganglions on the palm side of the wrist can be tricky to aspirate because they are near major vessels and nerves.

During an aspiration procedure, the fluid is drained from the ganglion cyst.

 Surgical Treatment

Your doctor may recommend surgery if your symptoms are not relieved by nonsurgical methods, or if the ganglion returns after aspiration. The procedure to remove a ganglion cyst is called an excision.

Surgery involves removing the cyst as well as addressing the stalk from which the cyst arises. This may mean removing part of the involved joint capsule or tendon sheath to ensure removal of the root of the cyst. Even after excision, there is a small chance the ganglion will return.

Excision is usually an outpatient procedure, meaning patients go home the day of surgery after a period of observation in the recovery area. There may be some tenderness, discomfort, and swelling after surgery. You are usually able to resume normal activities 2 to 6 weeks after the procedure.

A ganglion cyst at the wrist is removed during a surgical procedure called excision.

Ganglion cysts rarely, if ever, cause permanent disability. Cysts that do not go away on their own and cause symptoms almost always respond to surgery. In the rare case that a ganglion comes back after surgery, a revision surgery can be performed to remove the cyst again. After removal, most patients experience relief of symptoms.

Blog | Ganglion cysts (ganglion cysts)

• House
• Ganglion cysts (ganglion cysts)

A ganglion cyst is a fluid-filled lump under the surface of the skin that appears near joints and tendons. They usually do not cause any symptoms and often go away on their own. Treatment ranges from observation to outpatient surgery called a ganglionectomy.

What is a ganglion cyst

A ganglion cyst (plural ganglion) is a small, fluid-filled tumor just under the skin. Ganglia usually form close to the joint. Most ganglion cysts are on the wrist, finger, or foot.

How common are ganglion cysts

Many people develop ganglion cysts. Ganglia are one of the most common benign (noncancerous) formations that develop in the soft tissues of the body.

What causes ganglion cysts

Nobody knows exactly what causes ganglion cysts to grow. Some theories indicate that a cyst may develop after something damages the joint, causing tissue to leak or bulge.

Currently, most researchers agree that ganglion cysts develop from mesenchymal cells in the synovial-capsular junction as a result of continuous microtrauma. Repetitive damage to the supporting capsular and ligamentous structures appears to stimulate fibroblasts to produce hyaluronic acid, which accumulates to form the mucinous “jelly-like” material commonly found in ganglion cysts.

Who is prone to ganglion cysts

Based on what the medical community knows about ganglion cysts, anyone can get them. Certain factors can increase the chances of having one of these cysts. These factors include:

• Sex. Women develop ganglia three times more often than men.
• Age. Most people who develop a ganglion cyst develop it in early to middle age, between 20 and 50 years of age.
• Previous trauma. Some clinicians believe that trauma to the joint (eg, tendinitis due to overuse of the wrist) may trigger the development of a ganglion cyst in the future. Research has yet to confirm this theory.
• Arthritis. The presence of arthritis in the hands increases the likelihood of developing a ganglion cyst. People with arthritis often develop a ganglion cyst at their fingertips (in the joint closest to the nail). But having a ganglion cyst on your finger doesn’t mean you have (or will have) arthritis.

What are the symptoms of ganglion cysts

A bump under the skin is the main sign of a ganglion cyst. This bump can vary in size and shape. It may increase over time or as you use the area (the joint) more. The cyst may not bother you at all. If you have symptoms, you may notice some muscle pain or tingling at the site of the cyst. This is usually a mass effect, which means that the mass causes pressure and can cause inflammation.

Where ganglion cysts appear

Ganglion cysts usually appear in certain joints. Using a joint near the cyst can increase the swelling and any discomfort you feel.

Ganglion cysts usually develop on parts of the body such as:

• Wrist, front or back.
• Finger, near any joint of the finger (next to the palm or just below the nail).
• Foot, closer to the ankle or toes.

What a ganglion cyst looks like

A ganglion cyst usually looks like a swelling on the wrist, finger or foot. This bump may look symmetrical (round) or deformed (more like an oval).

The ganglion cyst is located just below the surface of the skin. It may look like a bubble is blown out of the joint. Ganglia sometimes have a translucent effect (can be seen through the lump at certain angles).

Ganglion cysts, hard or soft

People experience ganglion cysts differently. Ganglia are usually (but not always) hard to the touch. Some people report that fluid-filled cysts are soft. The bump will likely move easily under the skin.

How a Ganglion Cyst is Diagnosed

Ganglion cysts are usually diagnosed by healthcare professionals by doing a physical examination. The appearance and location of the lump (for example, on the wrist or fingers) are clear signs of ganglia. Your doctor may press on the bulge to see if it’s bothering you. Or he can shine a light on the bump to see if it is translucent (partially transparent).

In some cases, the doctor may take a sample from the lump (called a biopsy) for further analysis. Ganglia usually contain a jelly-like fluid rather than hard tissue. In rare cases, a doctor may recommend an x-ray to learn more about the mass if it is causing symptoms.

Your doctor may also use ultrasound to tell the difference between a solid mass and a cyst. There is also a difference between a ganglion cyst and a synovial cell. The difference lies in the composition of the cyst mucosa.

Can there be problems with an occult ganglion cyst

Some ganglion cysts are so small that they don’t cause obvious physical swelling, but still cause pain. They are known as the occult ganglia. Your healthcare provider may order magnetic resonance imaging (MRI) or ultrasound to look for them.

Do all ganglion cysts need treatment

If a ganglion cyst does not bother you, it may not need treatment. Sometimes a ganglion cyst goes away on its own.

Your doctor may recommend treatment if you have a ganglion cyst:

• Pain, which can happen when the cyst presses on a nerve or joint tissue.
• Makes certain movements or tasks difficult, such as walking or holding a pencil.
• Makes you feel ashamed of your appearance.

How ganglion cysts are treated

Treatment for ganglion cysts includes:

• Anti-inflammatory drugs. They will help minimize swelling and relieve mild discomfort.
• Splints or braces. Provides support and inhibits movement of the affected area, reducing swelling and pain.
• Aspiration is a procedure in which a doctor uses a needle to remove fluid from a cyst. Doctors usually do aspiration in their office. You may feel better right away. Because this treatment only removes the fluid and not the entire cyst, your symptoms may return.

When a ganglion cyst needs surgery

Your doctor may consider surgery if other treatments fail or your cyst comes back. Surgeons treat ganglia by removing the entire cyst. The cyst often includes a stalk-like structure (root) attached to the cyst.

Your surgeon may use open (traditional) techniques or arthroscopy (small incisions). In some cases, surgeons may remove tissue from a nearby joint to completely fix the problem.

Surgery to remove a ganglion cyst is called a ganglionectomy. This is usually an outpatient procedure. This means that you will be able to return home on the day of the operation. Full recovery takes two to six weeks. Orthopedic surgeons are specially trained to perform complex operations on the joints and other soft tissues of the body.

Surgery can effectively eliminate symptoms. Surgical removal of a ganglion cyst significantly reduces the risk of cyst recurrence. However, the ganglia return after surgery in about 5-15% of cases.

Is it possible to prevent ganglion cysts

You cannot prevent a ganglion cyst. Medical experts do not know what causes them to develop.

Are ganglion cysts dangerous?

Ganglion cysts are not dangerous. These are benign growths, which means that they will not spread to other areas. Ganglion cysts are not cancer.

What is the prognosis (outlook) for people with ganglion cysts

Although some ganglion cysts can be painful, they do not pose a serious threat to your health.

What questions should I ask my doctor

If you have a ganglion cyst, you can ask your doctor the following:

• Do I need treatment right now?
• What treatment options do you recommend I try first and why?
• What are the chances that the cyst will return after treatment?
• When would you consider surgical treatment of ganglion cysts?
• What are the risks and benefits of ganglionectomy surgery?

If you have a ganglion cyst, you may not need treatment right away. If it does not bother you, your doctor may monitor you for some time to see if there are any changes to the growth. Ganglion cysts are benign, which means that these growths are not cancer. They do not pose a long-term threat to your health. Many ganglion cysts disappear on their own. If a ganglion cyst is affecting your quality of life in any way, ask your doctor about treatment options. Splints, over-the-counter pain relievers, or surgery may help.
