Female, 48 years old, with blurry vision, prior history of optic neuritis. Evaluate for demyelinating lesions. Brain:A single T2 hyperintense, moderately T1 hypointense lesion is again seen within the periventricular white matter of the left parietal lobe. Accounting for differences in technique, this lesion has not substantially changed from the prior examination. No new white matter lesions are detected. Brain parenchymal morphology is unremarkable. No abnormal fluid collections are observed. The ventricular system is normal in size and morphology. A hypoenhancing lesion within the posterior pituitary gland, evident on the prior examination, is not as discretely visualized on today's study.Orbits:Within the limitations of mild motion artifact, no convincing signal abnormality is evident affecting either optic nerve, or the optic chiasm. No findings to suggest intraorbital inflammation are seen. The globes are round and symmetric. The extraocular muscles demonstrate normal morphology and signal characteristics.
1.A single white matter lesion is redemonstrated within the left parietal periventricular white matter showing no significant interval change. No new white matter lesions are identified in the brain.2.Within the limitations of a mildly motion degraded, noncontrast examination, no specific abnormalities of the optic apparatus are seen.
