Patient 1. Third MR examination at 2 weeks following relapse of the symptoms (10 weeks from initial onset).

A and B, Axial FLAIR images show multiple hyperintense lesions in the basal ganglia and thalami bilaterally, as well as in the left cerebellar peduncle and left dentate nucleus. A questionable small lesion is seen in the cortex (arrow in A).

C, Axial DWI shows a hyperintense lesion in the right caudate head (arrow), which was not depicted by either FLAIR or T2-weighted images (not shown).
