Brain magnetic resonance imaging of case 3. (Fluid attenuated inversion recovery axial images sequence)—bilateral hyperintensity of intra-orbital and intracranial optic nerves (R > L) as well as optic chiasm and right optic tract (horizontal white arrows). Bilateral normal orbital globes with no collections or masses. Generalized cerebral atrophy. Multiple bilateral scattered hyperintensities (vertical black arrows), no contrast enhancement when gadolinium was administered
