(A) Brain magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) on the first hospital day shows high signal intensity (HSI) at the internal capsule (upper and middle arrow) and splenium of the corpus callosum (lower arrow) on DWI (left) and subtle low signals on apparent diffusion coefficient (ADC) imaging (right) in the same area. (B) Brain MRI with DWI (left) and ADC (right) on the fourth hospital day shows disappearance of HSI on DWI, suggesting that the mechanism of encephalopathy was transient cytotoxic edema.
