Brain Magnetic Resonance Imaging. These two coronal FLAIR images demonstrate increased signal intensity within the cortical gray matter of the parietal, occipital and frontal lobes, with minimal involvement of the sub-cortical white matter. The deep white matter is spared. This picture is consistent with scattered regions of vasogenic edema most consistent with vasculitis, and not indicative of posterior reversible encephalopathy from hypertension.
