Headache and left ear tinnitus. Additional patient history includes systemic lupus erythematosus and optic neuritis. There is no evidence of intracranial hemorrhage, mass effect, or acute infarct. There are scattered foci of abnormal T2/FLAIR hyperintensity within the periventricular and subcortical white matter and along the undersurface of the corpus callosum, which are better appreciated on prior sagittal FLAIR imaging. No new lesions within the brainstem or elsewhere in the brain. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. There is a right lens implant.
1.Unchanged nonspecific white matter lesions in the supratentorial brain. Differential diagnosis again includes prior inflammation, demyelination, or ischemia.2. No new brainstem lesion is identified. Please note if high-resolution imaging of the eighth cranial nerves is warranted, dedicated MRI of the internal auditory canals can be obtained.
