title: An unusual appearance of an aneurysmal bone cyst of the thoracic spine.
abstract: Aneurysmal bone cysts (ABCs) have been reported in essentially every bone of the human skeleton. This case report documents a very unusual clinical appearance for this entity: a superior mediastinal mass. Also, the patient underwent multiple imaging studies that demonstrated both common (absence of septations) and unusual (extensive involvement of vertebral body with little involvement of posterior elements) characteristics of ABCs.
