Aneurysmal bone cysts are locally aggressive benign bone tumours with a high risk of recurrence. We describe a case in a 4-year-old girl, involving the right acetabulum. A direct posterior approach was used and the lesion ablated with curettage and local adjuvants with bone grafting. The cyst resolved swiftly with an uncomplicated recovery.
