Female, 63 years old, with metastatic disease to the brain status post radiosurgery. An enhancing lesion within the left occipital lobe is slightly smaller, now measuring 6 x 3 mm, previously 7 x 4 mm, with reduced edema.A small enhancing lesion within the right inferior cerebellum measures 7 x 6 mm, previously 8 x 6 mm, with minimal if any associated edema.A small focus of enhancement along the inferior vermis is unchanged. An adjacent focus of enhancement within the inferior left cerebellar hemisphere is slightly more conspicuous than on prior (see image 33, series 1301).A 5-mm focus of enhancement within the high right superior frontal gyrus is new. A 3-mm focus of enhancement within the left frontal operculum is new. A 2-mm focus of enhancement within the right superior temporal gyrus is also new. A questionable focus of enhancement along the margin of the left precentral gyrus is unchanged.No evidence of significant brain parenchymal edema or mass effect is seen. No significant intracranial hemorrhage or any abnormal extra-axial fluid collection is detected. The ventricles remain normal in size and morphology.
1.Lesions within the left occipital lobe and right cerebellum are stable to smaller.2.Two additional small lesions within the cerebellum are stable to minimally more prominent.3.Lesions within the right superior frontal gyrus, left frontal operculum and right superior temporal gyrus are new.
