MRI FLAIR sequence axial cuts (a, b) and ADC map (c) showing bilateral cerebellar, occipital cortical and subcortical as well as bilateral basal ganglia, frontal cortical, thalamic and brainstem patches and spots of abnormal bright signal (vasogenic edema) with a high ADC value. An MRI post contrast axial cut (d) shows posterior cerebellar patchy nodular and leptomeningeal enhancement.
