case_images: Brain and optic nerve abnormalities found in the first case admitted for acute vision loss associated with horizontal diplopia. (A) Orbital MRI showing tortuosity in the optic nerves with bilateral optic neuritis (T2 sequence). (B) Subcortical white matter lesions in brain MRI (T2 sequence).

case_images: FIG1
case_images: Orbital and brain MRI showed bilateral optic nerve sheaths and subcortical white matter T2 and FLAIR hyperintensities (Figure 1).

case_images: Brain and spinal abnormalities found in the second case presenting with rapidly progressive bilateral visual acuity deficit (VAD) associated with left hemifacial neuralgia. (A) Brain MRI showing periventricular hyperintensities on T2. (B) Spinal cord MRI showing both longitudinally extensive spinal cord lesions over three vertebral segments and segmented ones.
