[Dural arteriovenous fistula as a rare cause of intracerebral hemorrhage].

Dural arteriovenous fistulas are rare vascular malformations presenting with very different clinical signs, depending on the pattern of venous drainage. Retrograde leptomeningeal venous drainage is significantly correlated with a progressive neurological presentation. A case of a dural arteriovenous fistula with cortical venous drainage is presented. The draining vein was frankly aneurysmal dilated. Rupture of this venous aneurysm caused an intracerebral hemorrhage. The venous varix and the hematoma were microsurgically resected and evacuated.
