title: Intracranial, intradural aneurysmal bone cyst.
abstract: Aneurysmal bone cysts (ABCs) are benign, expansile, blood-filled, osteolytic lesions with internal septations that may be intraosseous or extraosseous. The cysts may cause local mass effect, and changes in the regional vascular supply necessitating intervention. A case of an intracranial, intradural ABC in a young male patient with progressively severe headaches is presented. This is only the third recorded intradural case, the majority of these rare lesions being extracranial and only a minute fraction intracranial.
