Figure 1: (a) T1W axial brain MRI showing hypointense lesions along cerebellar folia bilaterally (arrow), which are hyperintense on T2W image (arrow) (b). (c) These lesions do not enhance on postcontrast images. (d) They remain hypointense on fluid attenuated inversion recovery (FLAIR) sequence (arrow). (e) A large subpial dorsal cord lesion (horizontal arrow) with smaller cystic lesions located anterolaterally (vertical arrow) are also seen on T2W axial image
