27-year-old female experiencing paresthesias with previous abnormal MRI, evaluate for progression. A previously demonstrated subcentimeter enhancing lesion in the left occipital lobe with associated high T2 signal in the white matter deep to the visual cortex has resolved. Previous possible punctate focus of enhancement in the region of area postrema is not evident. There are no new lesions. There is no evidence of intracranial hemorrhage or acute infarct. 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 paranasal sinuses are unremarkable. Redemonstrated is a subcentimeter low intensity focus in the right frontal scalp, of indeterminate significance. There are several subcentimeter probable nasopharyngeal retention cysts, unchanged.
