Neurosarcoid: new onset tremors and ataxia. There is extensive cerebral and pontine white matter T2 hyperintensity. 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 skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There are bilateral lens implants.
Extensive cerebral and pontine white matter T2 hyperintensity is nonspecific, but may represent a manifestation of hypertensive encephalopathy. Otherwise, assessment for neurosarcoidosis is limited without intravenous contrast.
