Trace diffusion-weighted image of the brain demonstrates hyperintensity along the optic radiations [arrowheads in (A)], with corresponding hypointensity on ADC map [arrowheads in (B)], compatible with restricted diffusion. Restricted diffusion was also faintly present in the corpus callosum splenium [arrow in (C)] and dorsal pons [curved arrow in (D)].

Brain diffusion-weighted imaging demonstrated restricted diffusion of the corpus callosum, splenium, bilateral optic radiations, and dorsal pons (Figures 1A-D).
Axial post-contrast T1-weighted image through the cervical spine, ventral, and dorsal cervical nerve roots abnormally enhance [thin arrows in (B), compare to non-contrast image at same level in (A)].

MRI of the spine revealed symmetric cervical nerve root enhancement without spinal cord signal abnormality (Figures 2A,B).
