Figure 1: Magnetic resonance imaging of the brain showed chronic infarction in the right superior and middle frontal gyri with acute infarction in the right parietal lobe. Perfusion-weighted images were suggestive of vascular compromise involving both the cerebral hemispheres, which was more on the right side with sparing of the left occipital and posterior temporal lobes. Magnetic resonance angiography revealed multiple collateral vessels in both the posterior cerebral artery territories (more on left side), with prominent lenticulostriate vessels, features that are suggestive of Moyamoya disease
