PRES



The MRI above depicts a classic example of posterior reversible encephalopathy syndrome (PRES), sometimes also called reversible posterior leukoencephalopathy, an increasingly-recognized consequence of malignant hypertension.  The whitish areas ("hyper-intense signal") in the bilateral occipital and parietal lobes represent edema in these regions.  PRES has also been reported in other disorders such as eclampsia and lupus.  The lesion is allegedly reversible if the hypertension is appropriately treated.
