A ganglion cyst is a fluid-filled sack associated with a joint or tendon sheath. It most often occurs at the back of the wrist, followed by the front of the wrist.

The cause is unknown. The underlying mechanism is believed to involve an outpouching of the synovial membrane. Diagnosis is typically based on examination. The ability to shine light through the bump or any past decrease in size supports the diagnosis of the bump as a ganglion cyst. Ganglion cysts are usually obvious upon observation. Medical imaging may be considered on infrequent occasions to rule out another diagnosis.
