case_images: (a) Head computed tomography, (b) diffusion-weighted imaging and (c) T2*-weighted image revealed an enlarged pituitary fossa and suggested pituitary apoplexy. Contrasted magnetic resonance imaging (d: coronal, e: sagittal) showed mass lesions without enhancement. (f) There had been no infarction on admission .

case_images: Head computed tomography (CT) revealed an enlarged pituitary fossa [Figure 1a]. T2*-weighted imaging in a large tumor [Figures 1b-e]. There had been no cortical infarction [Figure 1f].
case_images: (a-b) Cervical and head magnetic resonance angiography showed left internal carotid artery occlusion but no occlusion of the intracranial artery due to cross-flow from the anterior communicating artery. (c) Arterial spin labeling imaging suggested hypoperfusion of the left hemisphere.

case_images: ASL on MRI. ASL on MRI showed decreased perfusion of the left hemisphere [Figures 2a-c].
case_images: Preoperative head computed tomography revealed a low-density area of only the left temporal lobe.

case_images: Emergency head CT revealed a low-density area in his left temporal lobe [Figure 3].
case_images: (a) Postoperative head magnetic resonance imaging showed the known ischemic stroke of the left temporal lobe but no newly high-intensity area. (b) Head magnetic resonance angiography revealed recanalization of the left internal carotid artery, and (c) arterial spin labelingshowed improvement of hypoperfusion of the left hemisphere.

case_images: Postoperative MRI showed recanalization of the left ICA and no fresh cerebral infarction except for a known temporal lobe stroke [Figure 4].
