Bilateral rather symmetrical white matter T2 & FLAIR hyperintensities with subtle T1 hypointensity are seen in the corticospinal tracts within the centrum semiovale and corona radiata, and in the posterior limb of internal capsule, thalami, midbrain, pons and medulla oblongata, the scanned upper cervical cord, as well as the cerebellar white matter.
Restricted diffusion is seen in these lesions with high DWI and low ADC signal indicative of cytotoxic; likely intramyelinic oedema.
