Metastatic NSCLC to brain status post SRS. Since May 2015, the left parietal lobe lesion has decreased in size, measuring up to 4 mm in diameter, and the enhancement associated with the tiny right parieto-occipital region lesion is no longer discernible, with only a residual punctate focus of susceptibility effect. There are scattered nonspecific punctate foci of susceptibility effect in the bilateral cerebral hemispheres. There is also nonspecific scattered T2 hyperintensity in the cerebral white matter. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
