NSCLC. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are a few scattered cerebral white matter T2 hyperintense foci. 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 orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
No evidence of intracranial metastases. A few scattered cerebral white matter T2 hyperintense foci are nonspecific, but may represent chronic small vessel ischemic disease.
