Swelling of the intraorbital segment of the right optic nerve of high T2 and T2 fat sat signal with enhancement on postcontrast sequences as well as thickening with the enhancement of the optic nerve sheath with inflammatory changes of the intraconal fat.
Normal appearance of the left optic nerve and optic chiasma.
No demyelinating lesions are seen at the infra or supratentorial level.
