Aneurysmal bone cyst of the zygomatic bone

摘要

Aneurysmal bone cyst (ABC) is a rare haemorrhagic, non-neoplastic lesion, most commonly seen involving the long bone and spine. It is characterised by its expansile nature, high vascularity and multi-cystic appearance. It is a rare lesion in the maxillofacial region with its occurrence more in the mandible than in the maxilla. So far only four cases of ABC in the zygoma have ever been reported in the English literature. Here we report a rare case of ABC of zygomatic bone with a short review.
