These are globular sac-like lumps or cysts that are formed from internal degeneration of a tendon. They are often found on the wrist and ankle on the long extensor tendons. Ganglion cysts are aspirated under local anesthesia.
1. Ganglion cysts are non-cancerous, but how they form is unclear.
2. Half of all ganglion cysts disappear without intervention.
3. The fluid within the cysts is somewhat similar to that contained within synovial joints.
4. Draining or surgically removing the cysts may prevent their return.
5. They most commonly occur next to the wrist joints, but they can affect the feet.
Removal of Ganglion Cyst
If the cyst is large or if it causes problems e.g. pain, removal may be necessary.
Aspiration: The fluid inside a cyst is similar to that which naturally occurs in joints. Removing it may permanently remove the cyst.
Open surgery: A small incision is made and the cyst is removed , together with the stalk.
