Newly diagnosed squamous cell carcinoma of the lung; need to complete staging with brain imaging History: newly diagnosed squamous cell carcinoma of the lung; need to complete staging with brain imaging. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are scattered foci of cerebral white matter T2 hyperintensity in the bilateral cerebral hemispheres. 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, and scalp soft tissues are grossly unremarkable. There is a left maxillary sinus retention cyst.
No evidence of intracranial metastases. Scattered foci of cerebral white matter T2 hyperintensity in the bilateral cerebral hemispheres are nonspecific, but may represent chronic small vessel ischemic disease.
