Aneurysmal bone cysts are benign but locally aggressive tumors, with 80% diagnosed in patients younger than 20 years. We report a case of a 7-year-old male who presented with pain in his right thigh due to a mi- nor injury and was diagnosed with a pathologic fracture in the distal femur. The fracture was fixed with plate and screws augmented with antibiotic-impregnated bone cement, and the histopathological analysis con- firmed the diagnosis of aneurysmal bone cysts.
