title: Aneurysmal bone cyst of the temporal bone.
abstract: Aneurysmal bone cysts are benign fibrosseous lesions of the bone that are rarely detected in the temporal bone. Seventeen cases of aneurysmal bone cysts with histological confirmation involving the temporal bone were reported in the literature. We report a case of left temporal aneurysmal bone cyst in a 52-year-old male with the clinical findings of periauricular painful swelling, decreased hearing, and facial paralysis. A magnetic resonance image of the patient showed a well-circumscribed multi-loculated expansile lesion of the left temporal bone during the first admission to the hospital. The lesion recurred 1 year after the subtotal resection with a more solid appearance. In addition, we review the literature for these rare lesions.
