    Abstract:
    A case was reported of a surgically removed idiopathic dural arteriovenous fistula of the superior sagittal sinus associated with intracerebral hemorrhage. Dural arteriovenous fistula of the superior sagittal sinus is said to be rare. Only 9 cases have been reported in detail so far. A 46-year-old male was referred to our clinic complaining of left motor weakness of sudden onset. He had no history of head injury. CT scan revealed subcortical hemorrhage in the right frontal lobe. enhanced CT scan showed string-like enhancement in the margin of the hemorrhage. Right internal carotid angiogram disclosed a dural arteriovenous fistula, of which the feeding artery was a meningeal branch of the posterior ethmoidal artery, draining the superior sagittal sinus and right frontal superficial cortical vein. The superior sagittal sinus was not obstructed. It was diagnosed as a rare idiopathic dural arteriovenous fistula in the superior sagittal sinus. Surgical obliteration of an arteriovenous fistula was performed preserving the superior sagittal sinus. Etiological aspects and surgical management of the rare lesion was discussed referring to previous reports.
