A STIR coronal sequence demonstrating hyperintense residual disease (arrow) in the left half of optic chiasma. B Axial diffusion-weighted sequence demonstrating diffusion restriction in the left half of optic chiasma. C T1 post-contrast coronal sequence showing peripheral contrast enhancement (yellow arrow) in the left optic nerve. Also noted is the loss of flow void (red arrow) of the cavernous portion of the left ICA, suggestive of thrombosis
