Abstract

Synovial chondromatosis is a proliferative chondrogenic benign tumor originating from the synovial membrane of the joint. Radiological findings occupy an important part in the diagnosis of patients with synovial chondromatosis, which appear in various forms, and are often misunderstood such as tuberculous arthritis and rheumatoid arthritis. In many cases, the findings of rice body, which are common in tuberculous arthritis and rheumatoid arthritis, and synovial chondromatosis are similar on magnetic resonance imaging. A case of primary synovial chondromatosis that was mistaken for tuberculous arthritis or rheumatoid arthritis by imaging findings is reported.
