Metastatic renal cell carcinoma to brain, completed whole brain RT 2/2015, surveillance scan. There is interval decrease in size of the enhancing lesion in the left precuneus, which now measures up to 5 mm, previously 7 mm. Likewise, the associated confluent surrounding T2 hyperintensity has diminished. The enhancing right inferior temporal gyrus lesion has also decreased in size, now measuring up to 3 mm, previously 6 mm. 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 a small amount of fluid in the mastoid air cells and retention cyst formation in the maxillary sinuses.
Interval decrease in size of the left parietal and right temporal lobe metastases and associated edema.
