Synovial chondromatosis of the temporomandibular joint: a case report.

Synovial chondromatosis is a rare benign condition. It most commonly affects the large joints. Presentation in the temporomandibular joint is rare. Our case was an incidental radiological finding and not diagnosed immediately, highlighting the ease with which conditions such as this can be missed, particularly in asymptomatic patients. Only 45% of patients with synovial chondromatosis show radiographic changes. Findings as significant as ours are unusual. An increased professional awareness of the radiological signs of synovial chondromatosis would be beneficial to improve diagnosis and prognosis for patients.
