 Multiple foci of T2 hyperintense signal in the periventricular, deep and subcortical white matter, as well as in the corpus callosum appear similar to the prior exam. No new lesions are identified. There is no associated enhancement. The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. Normal flow-voids are demonstrated in the major intracranial vascular structures. There is a subcentimeter probable Thornwaldt cyst. There is asymmetric fluid in the pneumatized left anterior clinoid process.
No appreciable change in the intracranial demyelinating lesions, without associated enhancement.
