A, Axial fast short-inversion-time recovery image with parameters of 520/20 (TR/TE) shows right optic-nerve enlargement (arrow) and a crescent-shaped collection of presumed fluid along the aural side of the right orbit (arrowhead), although funduscopic examination revealed greater retinal abnormalities on the nasal side.

B, Axial T2-weighted image with parameters of 4000/100 shows high-intensity signal in the region of the left lateral geniculate body (arrow).

C, Axial FLAIR image with parameters of 10000/120/2300 (TR/TE/TI) shows high-intensity signal in the region of the left occipital lobe (arrow).
