Multiple sclerosis [340], Reason for Study: ^Reason: eval for MS progression History: facial weakness There is no evidence of acute ischemic or hemorrhagic lesion on this scan.There are, however, multiple high signal intensity lesions on FLAIR images which appear to be showing perpendicular against lateral ventricle. The lesions are seen on the right frontal lobe deep white matter, right corpus callosum body, right posterior parietal subcortical white matter, left side corpus callosum splenium, periventricular white matter on the left lateral ventricle occipital horn, and mesial aspect of the left superior temporal gyrus close to the posterior aspect of the left insular. The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Multifocal high signal lesions on FLAIR which are consistent with multiple sclerosis lesions.No evidence of acute ischemic or hemorrhagic lesion.
