Left temporal/occipital lobe metastasis from a salivary gland malignancy treated via SRS. There is minimal residual patchy T2 hyperintensity, but no residual abnormal enhancement at the site of the treated left temporo-occipital region brain metastasis. There are a few scattered nonspecific foci of T2 hyperintensity without associated enhancement. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal 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 within the left mastoid air cells and mild mucosal thickening within the bilateral maxillary sinuses.
Interval involution of the treated left temporo-occipital region metastasis.
