Ganglion Cyst

Also known as: cyst, retinacular cyst, synovial cyst, bible cyst.

What is a ganglion cyst?

A ganglion cyst is a lump that frequently develops near joints or tendons of the wrist or hand. The contents of the cyst resemble joint fluid. The cyst can cause pain or limited mobility.

What causes ganglion cysts?

The cause of ganglion cysts is not entirely clear. One proposed mechanism by which ganglion cysts are thought to develop involves an outpouching of the lining of the joint or tendon sheath.

What are the symptoms of ganglion cysts?

Other than the physical presence of the lump on the skin, a ganglion cyst usually does not cause any other symptoms. However, sometimes, there may be pain, tingling, muscle weakness or numbness if the cyst compresses a nerve.

What are ganglion cyst care options?

In many cases, ganglion cysts do not require any treatment. When indicated, treatment options include external compression, drainage of the cyst with a needle (aspiration), and/or surgical excision of the cyst.
