Synovial cyst of the hip. An unusual pathology for the orthopedic surgeon. Apropos of 2 cases

: A synovial cyst of the hip was identified by CT scan in two cases of iliac and/or femoral vein compression. In one of these cases, incomplete resection required radical treatment of the underlying condition, osteoarthritis of the hip. The authors discuss the clinical signs, aetiopathogenesis and treatment of this disease which, although rare, has been frequently reported in the literature over the last decade.
