Brain metastases. There are multiple, greater than 10, supratentorial and infratentorial lesions with mild surrounding vasogenic edema. The largest of these lesions measures up to 10 mm in the left frontal lobe. Some of the lesions contain susceptibility effect, which may represent hemorrhage or calcification. Overall, the lesions appear to have increased slightly in size since December 2014. There is no evidence of acute infarct. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There are bilateral lens implants.
Multiple supratentorial and infratentorial lesions with mild vasogenic edema are compatible with metastases. The largest of these lesions measures up to 10 mm in the left frontal lobe. Overall, the lesions appear to have increased slightly in size since December 2014.
