FIG 1. MR images of the brain obtained during the patients first admission. The left putamen is hyperintense on T1-weighted images (A) and hypointense on T2-weighted (B) and FLAIR images (C). The left putamen (circles [D and E]) appears hyperintense on the exponential DW images (b = 1000-s/mm2 images divided by b = 0-s/mm2 images [5]) (D) and hypointense on the ADC maps (E). A subtle focus of reduced ADC is also present in the posterior aspect of the right putamen (arrows). Lipoma of the corpus callosum is incidentally noted (C, arrowhead).
