Ganglion
A ganglion is a cystic swelling in continuity with a joint capsule or tendon sheath. It is a degenerative disorder arising from the joint capsule. It is filled with clear, viscous fluid. Ganglia are common on the dorsum of wrist.
They are often painless and resolve spontaneously. Often, only reassurance of the patient is required. Wrist splints relieve the pain. Aspiration and injection are rarely effective. Surgical excision is best avoided as recurrance rate after surgery is quite high.
