What are Ganglion Cysts?
Ganglion cysts are lumps that can commonly develop in the hand, wrist, and fingers. They may be painless, but often times can be quite painful depending on their location. They are usually filled with clear gelatinous synovial fluid. They usually arise from the capsule of a joint or a tendon sheath. Ganglion cysts are usually not associated with any radiographic changes, although mucous cysts of the DIP may show the presence of arthritis and osteophyte formations. If the cysts are painful or bothersome they can either be aspirated or excised surgically.
