Aneurysmal bone cyst is a benign expansile bone lesion that mainly affects children and young adults. Despite its benign name, some of these lesions have a remarkable ability to destroy bone and grow rapidly. Treatment options of aneurysmal bone cysts include complete resection, curettage, curettage with bone grafting, selective arterial embolization (as a primary treatment or preoperative adjuvant therapy), and percutaneous injection of fibrosing agent. When possible complete excision is the treatment of choice. This study, we present a pediatric case of fibula aneurysmal bone cysts successfully treated with complete resection.
