title: Dural haemangioma with extracranial component.
abstract: A rare case of dural haemangioma with extracranial component is described. A subcutaneous frontal tumour was thought before operation to have originated in the skull. Angiography showed drainage into the superior sagittal sinus via a cortical vein. Dural haemangioma is thought to be a clinical rarity. Also, an arteriovenous malformation draining into the superior sagittal sinus is rarely encountered.
