Mandibular intraosseous lipoma: clinical features of a condylar location

Well-defined radiolucency in the left mandibular condyle (panoramic radiography).

(A and B) CT showing two different images of the osteolytic condylar lesion. (C) MRI demonstrating an enhancement of a unilocular lesion in the mandibular condyle. This focal condylar lesion presents with a well-defined and markedly dense ovoid morphology that adapts to the major axis of the left ascending ramus of the mandible.

Intraoperative articular aspect (condylar and glenoid fossa). An arthrotomy was performed via an endaural incision to gain access to the temporomandibular joint. Clinical and radiologic diagnosis was confirmed by surgical observations.

(A) The large tumour specimen in the central condylar cavitation had a whitish colour and a soft-elastic consistency. The margins of the surgical resection appeared to be tumour free. Histological diagnosis indicated a mandibular intraosseous lipoma. (B) Higher magnification of A.
