A head computed tomography (CT) scan demonstrated subtle, ill-defined regions of low attenuation involving his bilateral posterior temporo-occipital lobes (Figure 1).
A T2-weighted MRI image of his head shows bilateral, slightly asymmetric, multifocal T2 hyperintensities in the posterior temporo-occipital subcortical white matter. There were no DWI (image not shown) signal abnormalities to suggest ischemia. These findings are most consistent with vasogenic edema. Post-gadolinium images (image not shown) demonstrated no abnormal enhancement.

T2 hyperintensities in his bilateral temporo-occipital subcortical white matter, consistent with vasogenic edema (Figure 2). There were no diffusion weighted imaging (DWI) or apparent diffusion coefficient (ADC) signal abnormalities to suggest an acute infarction.
