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.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
