Abstract

Aneurysmal bone cysts (ABCs) are benign, non-neoplastic, expansile lesions. We present a case of a male patient aged 46 presented with 4-month history of left hip and low back pain and left hip swelling. Lumbosacral magnetic resonance imaging (MRI) and computed tomography (CT) demonstrated a large multi-loculated hemorrhagic lumbosacral and retroperitoneal mass with spinal dysraphism and tethered cord. Curettage and Biopsy were performed with partially resected cystic wall which was histological confirmed with aneurismal bone cyst. Large cystic mass of the vertebrae, sacrum, and pelvic bone must be considered with ABCs.
