Disease: Ganglion cyst

    Overview

    Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. They also may occur in the ankles and feet. Ganglion cysts are typically round or oval and are filled with a jellylike fluid.

    Small ganglion cysts can be pea-sized, while larger ones can be around an inch (2.5 centimeters) in diameter. Ganglion cysts can be painful if they press on a nearby nerve. Their location can sometimes interfere with joint movement.

    If your ganglion cyst is causing you problems, your doctor may suggest trying to drain the cyst with a needle. Removing the cyst surgically also is an option. But if you have no symptoms, no treatment is necessary. In many cases, the cysts go away on their own.

    Symptoms

    The lumps associated with ganglion cysts can be characterized by:

    • Location. Ganglion cysts most commonly develop along the tendons or joints of your wrists or hands. The next most common locations are the ankles and feet. These cysts can occur near other joints as well.
    • Shape and size. Ganglion cysts are round or oval and usually measure less than an inch (2.5 centimeters) in diameter. Some are so small that they can't be felt. The size of a cyst can fluctuate, often getting larger when you use that joint for repetitive motions.
    • Pain. Ganglion cysts usually are painless. But if a cyst presses on a nerve — even if the cyst is too small to form a noticeable lump — it can cause pain, tingling, numbness or muscle weakness.

    When to see a doctor

    See your doctor if you experience a noticeable lump or pain in your wrist, hand, ankle or foot. He or she can make a diagnosis and determine whether you need treatment.

    Causes

    No one knows exactly what causes a ganglion cyst to develop. It grows out of a joint or the lining of a tendon, looking like a tiny water balloon on a stalk, and seems to occur when the tissue that surrounds a joint or a tendon bulges out of place. Inside the cyst is a thick lubricating fluid similar to that found in joints or around tendons.

    Diagnosis

    During the physical exam, your doctor may apply pressure to the cyst to test for tenderness or discomfort. He or she may try to shine a light through the cyst to determine if it's a solid mass or filled with fluid.

    Your doctor might also recommend imaging tests — such as X-rays, ultrasound or magnetic resonance imaging (MRI) — to rule out other conditions, such as arthritis or a tumor. MRIs and ultrasounds also can locate hidden (occult) cysts.

    A ganglion cyst diagnosis may be confirmed by aspiration, a process in which your doctor uses a needle and syringe to draw out (aspirate) the fluid in the cyst. Fluid from a ganglion cyst will be thick and clear or translucent.

    Lifestyle and home remedies

    To relieve pain, consider an over-the-counter pain reliever, such as ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve). In some cases, modifying your shoes or how you lace them can relieve the pain associated with ganglion cysts on your ankles or feet.

    Things not to do

    An old home remedy for a ganglion cyst consisted of "thumping" the cyst with a heavy object. This isn't a good solution because the force of the blow can damage surrounding structures in your hand or foot. Also don't try to "pop" the cyst yourself by puncturing it with a needle. This is unlikely to be effective and can lead to infection.

    Risk factors

    Factors that may increase your risk of ganglion cysts include:

    • Your sex and age. Ganglion cysts can develop in anyone, but they most commonly occur in women between the ages of 20 and 40.
    • Osteoarthritis. People who have wear-and-tear arthritis in the finger joints closest to their fingernails are at higher risk of developing ganglion cysts near those joints.
    • Joint or tendon injury. Joints or tendons that have been injured in the past are more likely to develop ganglion cysts.
