Malignant neoplasm of right lung. The right frontal lobe lesion is no longer discernible and there is no evidence of new enhancing intracranial lesions. There are diffuse areas of white matter T2 hyperintensity bilaterally. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged 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 right maxillary sinus mucosal thickening.
The right frontal lobe metastasis is no longer discernible. Diffuse areas of white matter T2 hyperintensity bilaterally may represent treatment effects and/or chronic small vessel ischemic disease.
