 ORBITS: There is mild thickening and enhancement of the right optic nerve involving the intraorbital, intracanalicular and possibly the intracranial segments. The right optic nerve measures up to 7 mm in thickness while the left optic nerve measures up to 6 mm in thickness. There is no intraorbital or chiasmatic mass and no parasellar abnormality. The extraocular muscles are unremarkable.BRAIN: There is no evidence of intracranial hemorrhage, mass, or acute infarct.There are a few scattered patchy foci of T2 hyperintensity within the supratentorial white matter in a nonspecific pattern. 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 unremarkable. There is minimal paranasal sinus mucosal thickening.
1.Mild thickening and enhancement of the right optic nerve compatible with optic neuritis.2.Few scattered patchy foci of signal abnormality within the supratentorial white matter are nonspecific and may represent demyelinating lesions, chronic small vessel ischemic disease, among other etiologies.
