Swelling of the left optic nerve involving the retrobulbar intraorbital segment, extending to the intracranial segment up to the left aspect of the optic chiasma.
It elicits a high signal on T2 and T2 fat sat with enhancement. Mild enlargement of the subarachnoid space around the left optic nerve.
Normal appearance of the right optic nerve and orbital muscles.
No demyelinating lesion seen at infra-or supratentorial levels.
