There are multiple lesions in the supra and infratentorial brain. The dominant lesion is in the right centrum semiovale, with concentric rings of heterogeneous T1 hypointensity and T2/FLAIR hyperintensity. This lesion demonstrates patchy enhancement, with vivid abormal diffusion restriction (ADC value: ~250). There are multiple other smaller lesions, the larger ones which demonstrate a similar pattern - left centrum semi ovale, left cerebral crus, left hemipons. No susceptibility artifact. Normal visualised intracranial MRA. Incidental fluid filled sphenoid.
