Figure 1
MRI images at the beginning of illness (A1, B1, C1), end of 2nd week of illness (A2, B2, C2) and 8-weeks after onset of illness (A3, B3, C3). A1-3 are T1 weighted images showing no abnormality except increased generalized atrophy 2-weeks into the illness (A2) and some recovery by 8-weeks (A3). Diffusion weighted imaging (ADC map) showing restricted diffusion in bilateral thalami (arrows) 2-weeks into the illness (B2) and no diffusion restriction early in course (B1) and at recovery (B3). FLAIR imaging showing a hint of increased signal in thalami early in the disease (C1), more pronounced increased signal 2-weeks into the illness (C2), and recovery by 8-weeks (C3). Note increased generalized brain atrophy 2-weeks into the illness (A2, B2, C2) with some recovery by 8-weeks (A3, B3, C3).
