Four-dimensional maximum-intensity projection image reconstructed from computed tomography perfusion scan. a, b The right internal carotid artery and the right middle cerebral artery indicate delayed enhancement compared to the contralateral side. c In the late phase, the distal middle cerebral artery also exhibits delayed enhancement, and no stenosis or obstruction is observed, suggesting a proximal vascular lesion. d No venous abnormality was seen in venous phase
