A ganglion cyst is a fluid-filled bump associated with a joint or tendon sheath.[3] It most often occurs at the back of the wrist, followed by the front of the wrist.[3][4]
The cause is unknown.[3] The underlying mechanism is believed to involve an outpouching of the synovial membrane.[4] Diagnosis is typically based on examination. The ability to shine through the bump or any past decrease in size supports the diagnosis of the bump as a ganglion cyst.[4] Ganglion cysts are usually obvious upon observation. Medical imaging may be considered on infrequent occasions to rule out another diagnosis.[3][4]
Treatment is not necessary. Options for treatment include needle aspiration or surgery.[3] About half the time, they resolve on their own.[4] About three per 10,000 people newly develop ganglion of the wrist or hand a year.[5]
