case_images: Brain MRI showing bilateral hyperintense diffusion-weighted imaging signals (A, D) and decreased apparent diffusion coefficient (B, E) in the white matter of the frontal and parietal lobes. Axial fluid attenuated inversion recovery image was normal (C, F).

case_images: An urgent brain magnetic resonance imaging (MRI), performed within 2h of symptom onset, showed bilateral diffusion-weighted imaging (DWI) hyperintensities involving the subcortical white matter (Figure 1). There were also matching hypointensities on the apparent diffusion coefficient (ADC) map, but no signal change on fluid-attenuated inversion recovery (FLAIR) was observed (Figure 1).
case_images: Follow-up brain MRI at four weeks showing complete resolution of radiological abnormalities (A, C: axial diffusion-weighted imaging; B, D: Axial fluid attenuated inversion recovery images).
