Magnetic resonance imaging findings on day 3 of illness. (a) T2W images reveal mild hyperintensity in corresponding white matter thalami, with subtle and patchy restricted diffusivity T1 images demonstrating altered signals in periventricular white matter (arrows). Myelination is seen as appropriate for age. (b) Apparent diffusion coefficient (ADC) and Diffusion‐weighted imaging (DWI) reveal extensive restricted diffusion in periventricular and deep white matter, corpus callosum, internal capsule and along the pyramidal tracts.
