Metastatic lung cancer. Passed out last night, need to evaluate possible CNS disease. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are scattered foci of T2 hyperintensity in the cerebral white matter, which are nonspecific. There is also a nonspecific non-enhancing punctate focus of susceptibility effect in the right middle frontal gyrus. 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 mild mucosal thickening in the paranasal sinuses.
Nonspecific non-enhancing punctate focus of susceptibility effect in the right middle frontal gyrus. Otherwise, no evidence of intracranial metastases.
