Figure 1. Axial FLAIR image (a) of case 1 shows faint signal intensities on both parietal white matter. Diffusion image (b) fails to show any restriction which is consistent with PRES. Axial FLAIR image (c) of case 2 and corresponding DWI image (d) show increased signal intensities at bilateral occipital and parietal lobes consistent with PRES.
