Synovial chondromatosis: a case study and brief review

Synovial chondromatosis is a benign synovial neoplasm, most often monoarticular. A case involving a 25-year-old Hispanic woman with a 2-year history of joint stiffness, locking, and recurrent effusion is presented. The diagnostic evaluation included standard roentgenograms, magnetic resonance imaging, arthrocentesis, and arthrography. She underwent arthrotomy and synovectomy. Multiple small cartilaginous bodies were removed during the procedure. At 3-year follow-up, the patient has not reported any residual problems, except for mild joint stiffness. This paper will discuss the physical findings, diagnostic studies, and management of intra- or extra-articular synovial chondromatosis.
