Abstract
Synovial chondromatosis is an uncommon benign lesion in which the synovial membrane within the joint forms cartilaginous nodules and loose bodies due to cartilaginous metaplasia. It is rare to develop in the temporomandibular joint, and may be accompanied by cranial base expansion or temporal bone morbidity. A 41-year-old male patient visited our hospital complaining of preauricular pain and crepitus. On CT and MRI, increased synovial fluid in the joint cavity, loose body, temporal bone erosion and cranial base expansion were observed. It was diagnosed as synovial chondromatosis through imaging and clinical symptoms. After arthrocentesis, the symptoms slightly decreased, and arthrotomy was performed for complete resolution of the pain. The patient's pain and crepitus were resolved, and no recurrence of the lesion was observed.
