Figure 2. Brain MRI on the day of admission.
Diffusion-weighted sequences (A and C) demonstrate numerous cortical and subcortical foci of restricted diffusion in frontal and parietal lobes. On the FLAIR sequences (arrows B and D), these foci are only mildly hyperintense, consistent with acute embolic infarcts involving the anterior circulation.
MRI: magnetic resonance imaging; FLAIR: fluid-attenuated inversion recovery
