case_images: Magnetic resonance angiography showed bilateral dilated frontal cortical vein [Figure 1].
case_images: (a and b) Digital subtraction angiography showed a fistula (arrow) from the ophthalmic artery in the right internal carotid artery. (c and d) Digital subtraction angiography showed a fistula (arrow) from the ophthalmic artery in the left internal carotid artery.

case_images: (a) Lateral view of a selective injection of the left ophthalmic artery presenting a fistula (arrow). (b) Scepter XC was placed distal to the internal carotid artery to stabilize the guiding catheter and microcatheter (arrow). (c) 20% N-butyl cyanoacrylate (NBCA) diluted with oily contrast medium was infused into the fistula (arrow). (d) Lateral view of a selective injection of the right ophthalmic artery presenting a fistula (arrow). (e) Scepter XC was placed distal to the internal carotid artery to stabilize guiding catheter and microcatheter (arrow). (f) 20% NBCA diluted with oily contrast medium was infused into the fistula (arrow).
