Aneurysmal bone cyst--a lesion in the mandibular ramus.

The aneurysmal bone cyst occurs predominantly in the long bones and vertebral column although lesions have been seen in the clavicle, ribs, innominate bone, skull and bones of the hands and feet (Shafer et al., 1974). A case is reported of such a lesion presenting in the ascending ramus of the mandible.
