Left-sided blurred vision and eye pain There is subtle STIR hyperintensity with postcontrast enhancement involving the canalicular portion of the left optic nerve (series 4, image 19 and postcontrast series 12, image 8). The right optic nerve appears unremarkable. The globes, extraocular muscles, and intraorbital fat appear unremarkable bilaterally.Scattered foci of T2/FLAIR hyperintensity involving the white matter are again seen. Patchy areas of T1 hyperintensity involving the basal ganglia is nonspecific and may be metabolic. There is no evidence for acute ischemia or intracranial hemorrhage. Mild ethmoid sinus mucosal thickening is present.
1. Findings compatible with optic neuritis involving the canalicular portion of the left optic nerve.2. Scattered foci of T2/FLAIR hyperintensity involving the cerebral white matter are partially visualized, consistent with known demyelinating disease.
