(a): FLAIR Axial image showing thickening and increased signal intensity in the optic chiasm. (b): T-1 weighted post Gadolinium contrast Axial image showing enhancement in the left side of the optic chiasm. (c): FLAIR Axial image showing increased signal intensity in the bilateral optic tracts. (Left > right).

Brain and orbit magnetic resonance imaging (MRI) showed cystic encephalomalacia (14*9 mm) with surrounding gliosis in the posterior aspect of the right frontal lobe and T2 FLAIR high signal intensity in the left side of the optic chiasma and bilateral optic tracts with heterogeneous enhancement in the left side of optic chiasma, features suggesting demyelinating changes with active phase in the left side of the optic chiasma (Figures 1(a)-1(c)).
