45-year-old female with a history of optic neuritis. Evaluate for demyelinating lesions. Punctate foci of FLAIR hyperintensity in the left periventricular region are not seen on proton density imaging, favoring artifact. The prior left parasagittal lesion is not demonstrated on today's exam. There is continued optic nerve T2 hyperintensity.There is no evidence of intracranial hemorrhage, mass, or acute infarct. 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.
1.Punctate foci of FLAIR hyperintensity in the left periventricular region are not seen on proton density imaging, favoring artifact. 2.The previously described prior left parasagittal lesion is not demonstrated on today's exam. 3.There is continued optic nerve T2 hyperintensity indicating possible persistent optic neuritis
