case_images: fig1-2050313X231160885
case_images: Face was symmetric with no facial dysmorphic features (Figure 1).
case_images: Flash visual evoked potential revealed bilateral abnormal P100 latencies and
  no obvious waves in the both eyes.

case_images: fig2-2050313X231160885
case_images: The FVEP revealed bilateral abnormal P100 latencies and no obvious waves in the both eyes, demonstrating that our patient was totally blind (Figure 2).
case_images: Magnetic resonance imaging showing diffuse white matter T2 hyper-intensity in
  brain and brain stem (black arrows).

case_images: fig3-2050313X231160885
case_images: MRI reported diffuse white matter T2 hyper-intensity and T1 hypo-intensity in the periventricular, juxtacortical, and subcortical white matter with posterior brain stem, putamen, bilateral thalami, and cerebellum white matter involvement. Moreover, prominent Virchow-Robin Spaces (VRS) were seen (Figure 3).
case_images: Electroencephalography demonstrated diffuse slow and sharp (black arrows)
  waves.
