FLAIR axial images demonstrate abnormal high signal involving gray and white matter in the
right frontal and parietal lobes.
Another axial FLAIR image (left) confirms involvement of the left frontal cortex.
A diffusion-weighted (middle) image reveals restricted diffusion in the same areas, which are
confirmed as hypointensity on the ADC map (right).
MRA images (left) reveal multifocal narrowing of intracranial vessels, as do conventional
angiographic images (right), best seen in the middle cerebral arteries.
