Optic neuritis and history of type 2 diabetes, TIA one seizure episode associated with her TIA, hypertension, and smoking. Orbits: There is diffuse atrophy of the left optic nerve, without associated signal abnormality. The right optic nerve appears unremarkable. There is no evidence of mass lesions in the bilateral orbits. The globes, lacrimal glands, and extraocular muscles are unremarkable. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild scattered cerebral white matter T2 hyperintensity. There are subcentimeter foci of encephalomalacia in the right caudothalamic groove and left caudate. There is no abnormal intracranial enhancement. The ventricles and sulci are mildly prominent diffusely due to cerebral volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull and scalp soft tissues are grossly unremarkable. There is mild scattered paranasal sinus mucosal thickening. There are also several subcentimeter nasopharyngeal mucosal retention cysts.
1. Left optic nerve atrophy, without evidence of acute optic neuritis.2. No evidence of intracranial hemorrhage, mass, or acute infarct. 3. Subcentimeter foci of encephalomalacia in the right caudothalamic groove and left caudate likely represent chronic lacunar infarcts, superimposed upon a background of mild chronic cerebral white matter small vessel ischemic disease.
