Spells concerning for demyelinating disease: tremors and jerking. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are non-enhancing punctate foci of high T2 signal in the subcortical white matter of the left anterior insula and the anterior left temporal stem. There is a small developmental venous anomaly in the region of the left supramarginal gyrus. 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. Non-enhancing punctate foci of high T2 signal in the subcortical white matter of the left anterior insula and temporal stem are nonspecific. 2. Small developmental venous anomaly in the region of the left supramarginal gyrus.
