摘要

Aneurysmal bone cysts are benign, lytic, and locally aggressive bone lesions. They predominantly affect the long bones and vertebral column (50%), but can also be found in the scapula, ribs, and spine. Involvement of the jaw bones is rare, occurring in only 2–3% of cases, with the mandible being more commonly affected. ABCs account for about 1.5% of all non-odontogenic and non-epithelial jaw cysts. Treatment options include intra-cystic injections, embolization, surgical resection, and curettage. This case report presents a significant instance of an enormous ABC in the mandible of a 28-year-old male patient, which recurred despite undergoing an aggressive segmental resection of the mandible.
