case_images: A computed tomography (CT) scan of the patient's head was performed after he left the operating room, which confirmed that a mild subarachnoid hematoma had occurred [Figure 1].
case_images: (a) Magnetic resonance imaging indicating extensive infarction at the right middle cerebral artery territory. (b) Magnetic resonance angiography shows poor visualization of both middle cerebral arteries.
