Multiple hyperintense punctate lesions on T2-FLAIR sequences and hypointense in T1W sequences in the supra- and infratentorial white matter, predominantly affecting the corpus callosum (large size, tumefactive), subcortical white matter, centrum semiovale, left internal capsule and middle cerebellar peduncles.
Some of the lesions show restricted diffusion.
On gadolinium-enhanced T1W sequences, faint enhancement of some lesions is identified, particularly in the left corona radiata.
The optic nerves show normal morphology and signal intensity, without signs of optic neuropathy.
