Progression of metastatic lung lesions. The left cerebellar hemisphere enhancing lesion is no longer discernible. In addition, a left inferior sulcus lesion has decreased in size, measuring 6 x 8 mm in axial section, previously 9 x 11 mm. Otherwise, there is no significant interval change in size of the bilateral cerebral hemisphere peripherally enhancing tumors. For, example, a right superior frontal gyrus lesion measures 19 x 21 mm in axial section, previously 20 x 20 mm and a left middle frontal gyrus lesion measures 5 x 6 mm in axial section, previously 5 x 6 mm. There is a persistent mild degree of vasogenic edema associated with some of the lesions. Many of the lesions also display persistent susceptibility effect. There is no evidence of 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 left maxillary sinus retention cyst.
