Ganglion Cyst

A ganglion cyst is a benign fluid-filled lump that develops most often on the joints or tendons of the feet as well as the hands and wrists. While its exact cause is unknown, this type of cyst can develop either suddenly or over time and also can disappear on its own. It commonly occurs in women and in people between 20 and 40 years of age.

Symptoms

  • Raised, round, firm, fluid-filled lumps on the joints
  • Lumps that enlarge with joint use and decrease with rest
  • Pain, weakness and numbness (in some cases)

Treatment

  • Monitoring
  • Immobilization with a brace or splint
  • Needle aspiration to drain the fluid
  • Surgery to remove the cyst
