Small cell lung cancer restaging. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is unchanged predominantly periventricular white matter T2 hyperintensity. There is no abnormal intracranial enhancement. The ventricles and sulci are diffuse prominent due to cerebral volume loss. 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 and scleral buckle.
1. No evidence of intracranial metastases.2. Unchanged diffuse white matter abnormalities are nonspecific, but may represent chronic small vessel disease and/or treatment effects.
