Fig. 2. External carotid artery angiography demonstrate dural arteriovenous fistula at the mid-portion of a superior sagittal sinus. The meningeal arterial feeders enter the wall of the superior sagittal sinus, and, then drain through the dilated cortical veins (corkscrew vessels). The dilated cortical veins with venous hypertension, may be related to acute right intracerebral hemorrhage at the right parietal cortex.
