Ganglion Cysts

 

 

 

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

Small ganglion cysts can be pea-sized, with larger ones about an inch in diameter. If pressing on a nearby nerve ganglion cysts can be painful. Their location can sometimes interfere with joint movement.

If ganglion cyst is causing problems, doctor may recommend 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.

Causes of ganglion cyst is unknown. It grows out of a joint or the lining of a tendon, similar to 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 thick lubricating fluid similar to that found in joints or around tendons.

 


Joint or tendon injury. Joints or tendons, having been injured in the past, are more likely developing ganglion cysts.

Osteoarthritis. People, having wear-and-tear arthritis in the finger joints closest to their fingernails, are higher risk developing ganglion cysts near those joints.

Sex and age. Ganglion cysts can develop in anyone, but commonly occurring in women between the ages of 20 and 40.

 


A ganglion cyst is a fluid filled lump associated with a joint or tendon sheath. They most often occur at the back of the wrist followed by the front of the wrist. Onset is often over months. Typically there are no further symptoms. Occasionally pain or numbness may occur. Complications may include carpal tunnel syndrome……
