Female, 69 years old, with blurry vision. Evaluate for left optic neuropathy Numerous scattered foci of periventricular and subcortical white matter T2 hyperintensity are seen, progressed from the prior examination. No evidence of restricted diffusion is seen. No parenchymal edema or mass effect is detected. There is no abnormal parenchymal or extra-axial enhancement. No evidence of intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricular system is normal in size and morphology.The globes are round and symmetric. The extraocular muscles demonstrate normal caliber and morphology. The optic nerves and chiasm are morphologically normal and free of signal abnormality. No pathologic orbital enhancement is observed. Please note, however, that fat suppression failed in the right orbit likely due to underlying dental hardware which does limit the postcontrast evaluation of right orbital structures.
1.Interval progression of small vessel ischemic disease, with no findings to suggest acute intracranial abnormality.2.No specific orbital abnormalities are identified to account for the patient's symptoms.
