title: Synovial chondromatosis of the temporomandibular joint with middle cranial fossa extension.
abstract: Synovial chondromatosis of the temporomandibular joint (TMJ) is relatively rare. An unusual case with extension through the glenoid fossa and into the middle cranial fossa is reported. Invasion of the infratemporal fossa and the middle cranial fossa was seen on both computed tomography and magnetic resonance imaging. Complete removal of the loose bodies with excision of the affected synovium is the accepted treatment of synovial chondromatosis. A conservative approach should be followed while trying to eliminate any remaining lesion in the infratemporal fossa and the middle cranial fossa. An overview of previously reported cases of synovial chondromatosis with cranial extensions is also presented.
