Right optic neuritis, question demyelination. There is abnormal enhancement involving the prechiasmatic right optic nerve at the level of the optic canal and immediately posteriorly. Evaluation of the bilateral orbits is otherwise unremarkable without evidence of masses. Extraocular muscles appear unremarkable. Outside MRI from 2/11/2015 is limited however demonstrates some abnormal enhancement involving the right prechiasmatic optic nerve.Remainder of the brain demonstrates multiple foci of T2/FLAIR hyperintensity scattered in the supratentorial white matter. These lesions are nonspecific distribution although demyelination not excluded. Relatively largest of these focus is in the right parietal lobe and adjacent to prominent perivascular spaces.No intracranial mass or mass effect. No abnormal parenchymal or meningeal enhancement is seen within the remainder of the brain. Major flow-voids are preserved. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1. T2 hyperintensity and enhancement involving the right prechiasmatic optic nerve at the level of the optic canal and immediately posteriorly. Finding is compatible with optic neuritis. Outside study from 2/11/2015 is technically degraded but also demonstrates enhancement within this location.2. Multiple scattered T2/FLAIR hyperintensity in the periventricular and subcortical white matter in the brain have a nonspecific appearance and distribution and may reflect mild chronic small vessel ischemic disease or prior inflammation/infection, with demyelinating disease not entirely excluded. No abnormal enhancement is seen within the remainder of the brain to suggest an active infectious/inflammatory or neoplastic process.
