Metastatic lung cancer treated with WBRT: headaches. The supratentorial and infratentorial enhancing lesions are no longer conspicuous. There is unchanged patchy cerebral white matter T2 hyperintensity. There is no evidence of intracranial hemorrhage or acute infarct. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable. The clivus and left frontal bone lesions appear to be unchanged. There may also be a partly-imaged lesion in the C3 vertebra.
