Small cell lung cancer, initial staging: cough. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is scattered patchy cerebral and pontine white matter T2 hyperintensity. There is no abnormal intracranial enhancement. 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 is a right lens implant.
Findings suggestive of chronic small vessel ischemic white matter disease, but no evidence of intracranial metastases.
