Diffusion-weighted magnetic resonance imaging of spontaneous venous infarction and cortical hemorrhage complicating dural arteriovenous fistula.
Dural arteriovenous fistula (DAVF) is an abnormal arteriovenous shunt that occurs in the dura matter within or near a dural sinus. The clinical manifestations vary. The authors report herein a rare case of type III DAVF presenting with coexisting intracranial hemorrhage (ICH) and venous infarction evidenced by computed tomography (CT) and diffusion-weighted magnetic resonance imaging. Conventional angiography proved that the right middle meningeal artery and the occipital artery supplied the DAVF, with direct drainage into the cortical veins and superior sagittal sinus.
