A myxoid cyst (also known as a synovial cyst or mucous cyst) is a ganglion (tissue mass) of the adjacent joint, caused by leakage of fluid from the joint into the surrounding tissue.[1] These cysts often appear clinically with osteoarthritic symptoms and are a red or bluish colour, producing a gelatinous material if punctured.[2]
The cyst can be linked to the joint by injection of methylene blue; however, more recently, surgical techniques have been developed.[1] Common treatments consist of injection of corticosteroids, repeated puncture and drainage of the cyst or surgical excision. Total immobilization may lead to fixation of the joint and is not advised.[2]
