title: A case of dural arteriovenous fistula draining to the diploic vein presenting with intracerebral hemorrhage.
abstract: The authors report an unusual case of a dural arteriovenous fistula (dAVF) draining only to the diploic vein and causing intracerebral hemorrhage. A 62-year-old woman presented with disturbance of consciousness and left hemiparesis. Brain CT scanning on admission showed a right frontal subcortical hemorrhage. Digital subtraction angiography revealed an arteriovenous shunt located in the region around the pterion, which connected the frontal branch of the right middle meningeal artery with the anterior temporal diploic vein and drained into cortical veins in a retrograde manner through the falcine vein. The dAVF was successfully obliterated by percutaneous transarterial embolization with N-butyl-2-cyanoacrylate. The mechanism of retrograde cortical venous reflux causing intracerebral hemorrhage is discussed.
