30-year-old female with optic neuritis, evaluate for demyelinating lesions. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. 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 and scalp soft tissues are grossly unremarkable. Mild mucosal thickening of the bilateral maxillary sinuses.The optic nerves demonstrate no abnormal enhancement or increased T2 signal to suggest optic neuritis. There is ectasia of the optic nerve sheaths bilaterally as well as optic nerve sheath dilatation. In addition, there is questionable mild flattening of the left posterior globe and a slitlike appearance of the frontal horns of the lateral ventricles. The retro-orbital fat appears normal. No intraconal or extraconal lesions are identified.
