Synovial chondromatosis (SC) of temporomandibular joint (TMJ) is a rare benign disorder in which mesenchymal remnants of synovial tissue undergo cartilaginous metaplasia. It is usually confined to the superior joint space; however, it can occasionally extend beyond the joint capsule into the cranium, parotid gland, infratemporal fossa, or external auditory meatus. SC of TMJ with intracranial invasion is very rare. In this report, we present a case of a 56 year old female patient with a history of pain in left pre-auricular region and also highlight the importance of cone beam computed tomography (CBCT) for diagnosing very rare disorders like SC.
Keywords: Synovial chondromatosis, temporomandibular joint, loose bodies, metaplasia, cone beam computed tomography.
