Metastatic breast cancer to brain; s/p SRS and WBRT: surveillance. There is interval decrease in size of an enhancing lesion in the left superior parietal lobe, which measures 2 mm in diameter, previously 4 mm. There are unchanged subcentimeter lesions with susceptibility effect in the superior portion of the right precentral gyrus and left inferior parietal lobule. Other previously demonstrated intracranial lesions are no longer identified, accounting for differences in technique. There is no evidence of 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
