Lung cancer with brain metstases status post SRS and chemotherapy. There is a persistent subcentimeter focus of residual T2 hyperintensity at the grey-white matter junction of the left superior frontal gyrus. Otherwise, there is no evidence of residual or new abnormal intracranial enhancement. There is unchanged scattered mild nonspecific cerebral white matter T2 hyperintensity, particularly in the periventricular regions. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unchanged.
Persistent subcentimeter focus of residual T2 hyperintensity in the left superior frontal gyrus without evidence of recurrence of the treated brain metastases otherwise.
