Brain MRA was negative (Figure 1), but the MRI showed edema in the subcortical white matter of the right occipital lobe, right parietal lobe, and left occipital lobe, suggestive of posterior reversible encephalopathy syndrome (Figures2(a) and 2(b)).
Axial FLAIR images of the brain demonstrating hyperintense signals in the (a) posterior right parietal lobe and (b) posterior occipital lobes bilaterally.

Brain MRA was negative (Figure 1), but the MRI showed edema in the subcortical white matter of the right occipital lobe, right parietal lobe, and left occipital lobe, suggestive of posterior reversible encephalopathy syndrome (Figures2(a) and 2(b)).
Axial FLAIR images of the brain demonstrating slight improvement of hyperintense signals in the (a) posterior right parietal lobe and (b) posterior occipital lobes bilaterally.

The edema in the subcortical right parietal lobe appeared similar to the previous study (Figures 3(a) and 3(b)).
Axial FLAIR images of the brain demonstrating complete resolution of previously noted hyperintense signals in the (a) posterior right parietal lobe and (b) posterior occipital lobes bilaterally.

A repeat MRI showed interval resolution of previously described areas of signal abnormality that were affecting the occipital lobes and no evidence of an abnormal parenchymal signal (Figures 4(a) and 4(b)).
