The image quality scores are as follows: feeding artery: 3; nidus: 3, and draining vein: 3. (B) The nidus and the draining veins (arrowhead) were faintly seen on TOF MRA. The image quality scores are as follows: feeding artery: 2; nidus: 1, and draining vein: 2. (C) The front view of the left internal carotid artery angiography showed the nidus (arrowhead).
