Abstract

A 54-year-old woman with a history of severe rheumatoid arthritis presented with painful swelling of the left lower limb. Computed tomography showed a large synovial cyst of the underlying hip joint with femoral vein compression. We also observed proximity of the cyst to the surrounding structures and communication between the cyst and the hip joint cavity.
