 Redemonstrated are numerous patchy foci of T2 hyperintensity within the supratentorial and infratentorial white matter. The supratentorial foci are mainly clustered in a periventricular distribution with extensive involvement of the entire corpus callosum. There is also involvement of the bilateral basal ganglia and thalami extending into the brainstem which is extensively involved. 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 scalp soft tissues are unremarkable. The paranasal sinuses and mastoid air cells are clear.
1.Extensive supratentorial and infratentorial non-enhancing T2 hyperintense lesion burden consistent with patient's diagnosis of multiple sclerosis.2.No restricted diffusion to suggest the presence of acute ischemia.
