A Giant Aneurysmal Bone Cyst in the Mandibular Condyle.

Aneurysmal bone cyst (ABC) is a rare, rapidly expanding, locally destructive, and easily misdiagnosed lesion. An ABC of the condyle is rare. This report presents a 25-year-old female with a giant ABC in the left mandibular condyle. This patient was treated with surgical resection of the affected bone and immediate mandibular reconstruction using autologous bone. Follow-up to date showed no signs of recurrence. The clinical feature, imaging finding, pathogenesis, and treatment methods of ABCs are discussed. (C) 2016 by Mutaz B. Habal, MD.
