Ganglion cyst - A ganglion (GANG-lee-on) cyst is a firm, fluid-filled lump that can suddenly appear on the front or back of the wrist or at the base of a finger. These cysts grow from normal issue in the wrist and fingers, and range in size from a pea to a peach pit. Although ganglion cysts are common, they don’t spread, and they don’t become cancerous. They can occur after an injury, but many times it isn’t known why they grow. Ganglion cysts can change in size and may go away on their own.

Treating a Ganglion Cyst

Your doctor may just watch your ganglion cyst. Many shrink and become painless without treatment. Some disappear altogether. If they cyst is unsightly or painful, or makes it hard for you to use your hand, your doctor can treat it or, if needed, remove it surgically.

Nonsurgical Treatment

To shrink the cyst, your doctor may remove (aspirate) the fluid with a needle. If the cyst hurts, your doctor may also give you an injection of an anti-inflammatory, such as cortisone, to relieve the irritation. Your hand may then be wrapped to help keep the cyst from recurring.

Surgery

If the cyst reappears after treatment, your doctor may remove it surgically. A section of the tissue that lines the joint or tendon is removed along with the cyst. This helps prevent another cyst from forming. Usually, only your hand or arm is numbed, and you can go home a few hours after surgery. Your hand may be in a splint for up to several weeks.
