Ganglion Cysts

Presentation

The patient is concerned about a rubbery, rounded swelling most commonly emerging from the dorsal or volar aspect of the wrist or the flexor tendon sheath of the hand. It may have appeared abruptly, been present for years, or fluctuated, suddenly resolving and gradually returning in much the same place ( Fig. 111.1 ). The patient often first notices it when a minor injury brings it to attention. People may be troubled with these cysts at any age, but they tend to be most common in midlife.

There is usually little tenderness, inflammation, or interference with function, but ganglion cysts may be bothersome with symptoms that include pain, paresthesias, limitation of motion, or weakness. Often the patient is only disturbed by the presence of a lump.
