Female, 88 years old, with metastatic breast cancer to the brain status post SRS to left frontal and right parietal lesions on 06/30/16. Evaluate for response and for new lesions. A prior right basal ganglia lesion was not treated. The left precentral gyrus enhancing lesion has decreased in size, now measuring 3 mm in diameter, previously 9 mm. Associated edema has also improved. The right postcentral gyrus enhancing lesion has also decreased in size measuring about 2 mm in diameter, previously 7 mm. Associated edema has resolved. The enhancing lesion in the right caudate head has increased in size now measuring up to 5 mm, previously 3 mm.No new enhancing lesions are seen. No areas of significant generalized edema or mass effect are detected. Scattered nonspecific foci of T2 hyperintensity are not significantly changed. No abnormal extra-axial collections are detected. The ventricles remain normal in size and morphology.
1.The treated left precentral and right postcentral gyrus lesions both demonstrate interval reduction in size.2.The untreated right caudate head lesion has increased slightly in size.3.No new lesions are seen.
