Known brain metastases from lung cancer status post recent whole brain radiation. There are four supratentorial ring-enhancing mass lesions with surrounding vasogenic edema. The right parietal lobe tumor measures up to 42 mm, the right occipital lobe tumor measures up to 12 mm, the left temporal lobe tumor measures up to 8 mm, and the left superior frontal gyrus tumor measures up to 7 mm. There is susceptibility effect along the walls and layering within the right parietal lobe tumor. There is also a nonspecific punctate focus of enhancement in the right lateral pons. There is no evidence of acute infarct. There is effacement of the right lateral ventricle, but no evidence of hydrocephalus. There is trace midline shift to the left and perhaps minimal subfalcine herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Multiple brain metastases, the largest of which measures up to 42 mm in the right parietal lobe and demonstrate intratumor hemorrhage.
