Sole radiographic expression of rheumatoid arthritis in the temporomandibular joints: a case report

We present an unusual case of rheumatoid arthritis. The patient had no radiographic findings in any joints of the body expected to show symptoms of the disease, such as phalangophalangeal joints of the hands and metacarpophalangeal joints. Instead, the patient had radiographic findings in the temporomandibular joints, which are not commonly involved in the disease and its activity.
