Aneurysmal bone cyst of temporal bone

Aneurysmal bone cysts (ABC) are benign neoplasms frequently occurring in the long tubular bones. It is very rare in temporal bone. We report a case of ABC of the left temporal bone in an 8-year-old Asian boy who presented clinically with swelling over the left temporal region for 5 months. CT and MRI features were suggestive of ABC. Surgical resection was performed and on follow-up the patient was doing well. CT and MRI are the imaging modalities for proper evaluation of ABC, aiding to diagnosis and helpful in treatment planning.
