Clinics in diagnostic imaging (122).

A 37-year-old Indian man presented with a two-year history of right hip pain. Radiographs showed small faint dense nodules at the inferomedial aspect of the right hip joint. Diagnosis of synovial osteochondromatosis was made on MR imaging, where multiple ossified loose bodies surrounded by a joint effusion, as well as enhancing synovium, were seen. Synovectomy and removal of 31 loose bodies were performed, and the diagnosis was confirmed histologically. The clinical manifestations and imaging features of synovial osteochondromatosis are discussed.
