Transient Global Amnesia with Reversible White Matter Lesions: A Variant of Posterior Reversible Encephalopathy Syndrome?

Figure 1

(a) Fluid attenuation inversion recovery (FLAIR) images of MRI on admission were interpreted as normal, but in retrospect, they show an indistinct high-intensity area in the right frontal subcortical white matter (arrowhead). (b) FLAIR images of MRI on the next day reveal high-intensity areas, presumed to be vasogenic edema, in the right frontal, bilateral parietal, and left occipital subcortical white matter (arrowheads). (c) The repeat MRI performed one month later shows the disappearance of all lesions.
