Metastatic lung caner the to brain: followup scan. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is unchanged patchy cerebral white matter T2 hyperintensity bilaterally. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is a partially empty sella. 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. There is an unchanged nonspecific subcentimeter focus of enhancement in the left occipital bone.
Post-treatment effects in the brain, without evidence of active intracranial metastatic disease.
