Initial brain magnetic imaging resonance (MRI). (A) Axial section showed hyperintensity on right posterior medial temporal lobe on diffusion-weighted imaging (DWI) (A I) without apparent diffusion coefficient hypo intensity (A II), with associated T2-weighted-fluid-attenuated inversion recovery (T2-FLAIR) hyperintensity (A III), and coronal section T2-weighted imaging showed no hyperintensity on midbrain and thalamus (A IV). Two days later brain MRI (B) axial section showed persistent DWI hyperintensity on right posterior medial temporal lobe (B I), without ADC hypointensity (B II), persistent T2-FLAIR hyperintensity (B III), and unchanged coronal section T2 weighted imaging (B IV; lesion pointed by arrow).
