consisting of villous lipomatous proliferation of the synovium that tends to occur in the knee joint, especially in the suprapatellar pouch (1). The lesion has been observed in other locations, including the glenohumeral joint, subdeltoid bursa, hip, and elbow (2). It may be similar to other proliferations of the synovial membrane, but the characteristic feature is the macroscopic hypertrophic ...

This is the case report of a 65-year-old man who experienced left calf pain after spraining his left ankle.
