Fluid attenuated inversion recovery
magnetic resonance imaging showed a high intensity signal in the sulci of the left parietal lobe and bilateral occipital lobe (Figures 1(a) and 1(b)).

A corresponding fluid attenuated inversion recovery
(FLAIR) image (FIGURE 1B) shows an abnormal parenchymal signal and hyperintensity in the left occipital lobe, which is the area of the stroke.
