Numbness and tingling unilaterally. There are several, approximately 10, scattered punctate T2 hyperintense supratentorial lesions in the periventricular and subcortical white matter. Some of the lesions are T1 hypointense. There is no abnormal intracranial enhancement. There is a small nodular convex contour of the right lateral aspect of the medulla. The brainstem and cerebellum otherwise appear to be unremarkable. 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 orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. Findings suggestive of demyelinating disease, such as multiple sclerosis.2. A small nodular convex contour of the right lateral aspect of the medulla may represent an accessory cuneate nucleus rather than neoplasm or heterotopion.
