tokens: RESULTS : Initial MRIs showed abnormal high signal intensities on DWI and FLAIR ( or T2 - weighted image ) at the dentate nucleus ( 8 / 8 ), inferior colliculus ( 6 / 8 ), corpus callosum ( 2 / 8 ), pons ( 2 / 8 ), medulla ( 1 / 8 ), and bilateral cerebral white matter ( 1 / 8 ). High - signal intensity lesions on DWI tended to show low signal intensity on ADC map ( 3 / 4 ), but in one patient , high signal intensity was shown at bilateral dentate nuclei on not only DWI but also ADC map .
