case_images: Brain MRI images (T2-FLAIR sequence) for case 1: Axial (A-C):
  Hyperintensities seen over bilateral temporal, frontal and parietal
  lobes during initial presentation. Axial (D-F): Resolving signal
  abnormalities in his repeated scan done a month later.

case_images: His brain magnetic resonance imaging (MRI) showed abnormal signals over bilateral frontal, temporal and parietal lobes involving both the cortex and white matter, and these lesions were non-enhancing (Figures 1A-1C). His repeated brain MRI a month later showed substantial reduction in the signal intensities (Figures 1D-1F).

case_images: Brain MRI images for case 2: Axial (A) shows hyperintensity in the
  right lateral dorsal pons on T2-FLAIR sequence with (B) Contrast
  enhancement seen on T1 weighted sequence. Coronal (C-D) T1 weighted
  pre-and post-contrast respectively. Axial (E-F) thin-sliced T1
  weighted gadolinium sequence to illustrate the enhanced lesion
  occurs above the entry of trigeminal nerve. (black arrow): indicates
  the lesion. (white arrow): indicates the trigeminal nerve.

case_images: fig2-11795735221102747
case_images: T2-weighted and fluid attenuated inversion recovery (FLAIR) hyper-intensities in the right lateral dorsal pons, at the level above the entry of trigeminal nerves. This lesion was contrast-enhancing without demonstrable restricted diffusion (Figure 2).
