A–E, T2-weighted axial sections demonstrating the involvement of cortical gray matter, white matter, thalami, brain stem, and cerebellar hemispheres. F–I, DWI axial sections demonstrating diffusion restriction in thalami, cerebral, and cerebellar white matter. Trilaminar pattern on ADC (G) as a low signal ring (arrows) with central and peripheral hyperintensity. J and K, SWI demonstrating microhemorrhages in thalami and brain stem.
