A, Right external carotid artery angiogram shows meningeal and accessory meningeal arteries (arrows) communicating with a segment of the occluded left sigmoid sinus (asterisk).
B, Venous phase image of the right external carotid artery angiogram shows drainage of the AVM through the tentorial sinus, basal vein of Rosenthal, and orbital veins. Note the reflux into the cortical veins (arrows) and the superior sagittal sinus (arrowheads).
