Abstract

Aneurysmal bone cyst is relatively rare, benign tumor in the adolescent. An aneurymal bone cyst in the skull base is much more rare. This lesion is frequently accompanied with other conditions such as fibrous dysplasia, osteosarcoma, and chondroblastoma. The differential diagnosis is important;however it is difficult to make a correct diagnosis. The diagnosis is usually made from CT and pathological findings such as multi-lobulated, thin-walled cyst filled with blood. The treatment of choice is complete excision, if possible. We experienced a case of aneurysmal bone cyst arising from petrous bone, which was treated with transtemporal approach with partial excision. The patient remains free of symptom for 24 months with some tumor remaining in the clival area.
