Postbleed day 5 MRI with TOF angiography. MRI = magnetic resonance imaging and TOF = time of flight. (A) Axial TOF sequence at the level of the pons displaying severe basilar artery spasm (white arrow). (B) Axial TOF sequence at the level of the mesencephalon displaying severe right middle cerebral artery vasospasm (white arrow). (C) Three-dimensional TOF reconstruction of the circle of Willis displaying severe spasm of the basilar artery trunk and the middle cerebral arteries bilaterally. The vasospasm is severe enough to prevent TOF signal from identifying the distal basilar and the left proximal middle cerebral artery.
