case_images: Brain magnetic resonance imaging on the second day after onset. Brain MRI showed diffusion restriction in diffusion-weighted imaging (DWI) and hyperintensity of fluid-attenuated inversion recovery (FLAIR) in the bilateral parieto-occipital lobe on the second day after onset.

case_images: Brain magnetic resonance imaging (MRI) on the second day after onset (Figure 1) revealed restricted diffusion in diffusion-weighted imaging (DWI) and reduced apparent diffusion coefficient (ADC) in the bilateral parieto-occipital lobes.
case_images: Brain magnetic resonance imaging in follow-up. Brain MRI showed new diffusion-weighted imaging (DWI) diffusion restriction in the splenium of the corpus callosum, and diffusion restriction of the parietal and occipital lobes was lower than before on the eighth day of onset (A-C). Brain MRI revealed the lesions in the bilateral parieto-occipital lobe and splenium of the corpus callosum disappeared, leaving slight atrophy of the bilateral occipital lobe after 4 months (D-F).

case_images: On the eighth day of onset, the second brain MRI (Figures 2A-C) showed new restricted diffusion in the splenium of the corpus callosum, and hyperintense signal of the parietal and occipital lobes in DWI was lower than before. Four months later, brain MRI (Figures 2D-F) showed that the abnormal signals in the bilateral parieto-occipital lobes and the splenium of corpus callosum disappeared, leaving slight atrophy of the bilateral occipital lobe with microbleeds.
