Axial MRI obtained prior to clinical deterioration revealing scattered vascular hyperintensities on FLAIR sequences in bilateral sylvian fissures and over the cerebral cortex (A and B, FVH indicated by the arrows).

Initial MRI of the brain revealed scattered subcortical T2-hyperintense lesions (Fig 1), however, close inspection in retrospect reveals FVH (arrows) in bilateral sylvian fissures and other sulcal locations corresponding to middle and posterior cerebral artery (middle cerebral artery [MCA], PCA) segments.
Axial FLAIR and diffusion-weighted MRI obtained after clinical deterioration revealing parenchymal high signal in the bilateral temporal-parietal-occipital regions that demonstrate restricted diffusion indicating ischemic stroke.

MRI acquired shortly after this event revealed bilateral acute ischemic strokes in the territories adjacent to the previously noted FVH (Fig 2).
