Imaging of osteochondroma of the temporomandibular joint – Report of two cases

Abstract

Osteochondroma of mandibular condyle is an uncommon entity. In the temporomandibular region, they usually present as restriction in mouth opening and pain in the joint. They can grow to a large size to impinge upon the cranial fossa. We present the imaging features of two such rare cases, one was giant condylar osteochondroma and the other one was condylar osteochondroma associated with contralateral osteochondroma of the zygomatic process of the temporal bone and congenital block cervical vertebrae. Computed tomography, magnetic resonance imaging of the temporomandibular joint and bone scan findings are discussed in detail along with the follow-up of patients.
