Case Discussion

In posterior reversible encephalopathy syndrome, there is vasogenic edema within the occipital and parietal regions, relating to the posterior cerebral artery supply. The edema is usually symmetrical. Despite being termed posterior, posterior reversible encephalopathy syndrome can be found in a non-posterior distribution, mainly in watershed areas, including within the frontal, inferior temporal, cerebellar, and brainstem regions. Both cortical and subcortical locations are affected.
