NAION (non-arteritic anterior ischemic optic neuropathy), right eye. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are minimal scattered nonspecific cerebral white matter foci. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.Orbits: There appears to be mild atrophy of the right optic nerve along with perhaps mildly high T2 signal in the anterior portion of the optic nerve. The left optic nerve appears unremarkable. There is no abnormal intraorbital enhancement or mass lesions. The bilateral globes and ocular adnexa are unremarkable.
1. Possible mild atrophy of the right optic nerve, which may represent a sequela of non-arteritic anterior ischemic optic neuropathy.2. No evidence of intracranial hemorrhage, mass, or acute infarct.
