Metastatic head and neck cancer with new brain lesion. There is a presumably ring-enhancing mass that measures up to 12 mm in the left superior frontal gyrus with associated vasogenic edema. There is a defect in the left caudate head, which may represent a chronic lacunar infarct. There are also a few punctate foci of nonspecific T2 hyperintensity in the cerebral white matter. There is no midline shift or herniation. There is no evidence of hydrocephalus. The skull, orbits, and scalp soft tissues are unremarkable.
Limited treatment planning MRI demonstrates a mass that measures up to 12 mm with associated vasogenic edema in the left superior frontal gyrus, which is compatible with metastatic disease.
