MRI findings. (Top) MRI on day 4 of illness. Restricted water diffusion was observed in the corpus callosum and deep white matter. (A) Diffusion-weighted images, and (B) apparent diffusion coefficients map. (Middle) MRI on day 10 of illness. No MRI abnormalities were seen. (C) Diffusion-weighted images, and (D) apparent diffusion coefficients map. (Bottom) MRI of a prior MERS episode at 110 months of age. A similar pattern of restricted water diffusion is evident in the corpus callosum and deep white matter. (E) Diffusion-weighted images, and (F) apparent diffusion coefficients map. MERS, Mild encephalitis/encephalopathy with a reversible splenial lesion.
