Figure 2.

The brain MRI images of the proband. In the “stroke-like” episode, brain MRI showed slightly hypointensity in T1-weighted imaging (A) and slightly hyperintensity in T2-weighted imaging (B) in the bilateral deep white matter and the splenium of the corpus callosum. But there was obviously bilaterally symmetric hyperintensity in T2 FLAIR images and reduced diffusion in the same region (C,D). MRI after 8 days showed improvement of the abnormal diffusion signal in white matter (E). After 5 months, the images of T1-weighted (F), T2-weighted (G), T2 FLAIR (H), and DWI (I) of his brain were almost normal.
