 There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is redemonstration of several scattered punctate foci of abnormally increased T2/FLAIR signal within the supratentorial white matter without definite change from 2/20/2015 when accounting for differences in technique. 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 midline structures and craniocervical junction are within normal limits. The skull and scalp soft tissues are unremarkable. There is minimal paranasal sinus mucosal thickening. The optic nerves are incompletely evaluated on this examination.
Several scattered foci of signal abnormality within the supratentorial white matter not significantly changed accounting for differences in technique. Lesions are nonspecific and may represent demyelinating disease or chronic small vessel ischemic disease among other etiologies.
