ganglion
Last reviewed 09/2021
A ganglion is a 'cyst' arising from a joint or tendon sheath, most commonly around the wrist. The 'cyst' is formed by the distension of small bursae within the substance of the joint capsule.
Presentation of this condition is often in a young adult with a painless lump, usually on the back of the wrist. Sometimes the patient may complain that the lump aches. On examination the lump is well-defined and not tender. It is cystic, and may be attached to one of the tendons.
This condition may disappear after some months without treatment. If the lump is troublesome then it may be aspirated. If the lump recurs it may be injected with steroids.
