Aneurysmal Bone Cyst presenting Incidentally as a Traumatic Foot Injury

Introduction: Aneurysmal bone cyst is a rare, non-neoplastic lesion affecting the metaphysis of long bones and vertebrae, characterized by blood-filled spaces separated by fibrous septae. Aims and objectives: In this study, we present a case of an aneurysmal bone cyst in a 7-year-old child with characteristic X-ray findings to increase awareness as early diagnosis and treatment can limit disability. An aneurysmal bone cyst is a rare, benign neoplastic lesion affecting the metaphysis of long bones and vertebrae, characterized by blood-filled spaces separated by fibrous septae.[1] Diagnosis depends on typical features of magnetic resonance imaging, and confirmation by biopsy is essential before surgery is considered.   We present an aneurysmal bone cyst in a 7-year-old child with characteristic X-ray findings. Diagnosis of ABC should be suspected in young patients presenting with limb pain or swelling, and pain disproportionate to the mechanism of injury could indicate pathologic fracture. Early detection of ABC is possible as an incidental finding by closely examining routine X-rays so that appropriate treatment can be instituted early and complications like pathologic fractures can be avoided. This case will help to increase awareness as early diagnosis and treatment can limit disability.
