Demyelinating lesions. Left leg weakness. There are numerous, greater than 10, foci of supratentorial and infratentorial white matter T2 hyperintensity. In addition, a few of the lesions demonstrate enhancement, particularly in the right frontal lobe, including an open-ring enhancement pattern. There is no evidence of intracranial hemorrhage, mass, 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 orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Findings compatible with demyelinating disease, particularly multiple sclerosis with areas of active demyelination.
