Figure 1: Upper panel (a-d) First T2W MRI images show no evidence of abnormal signal intensity in periventricular white matter, however subtle abnormal hyperintense signal along posterior limb of internal capsule and cortico-spinal tracts are seen. Lower panel (e-h) Follow-up T2W MRI images shows confluent hyperintense signal intensity in parieto-occipital periventricular white matter and bilateral cerebellar peduncles and adjacent cerebellar hemispheres. The abnormal signal in internal capsule and cortico-spinal tract become more extensive
