Breast cancer with brain metastases: surveillance. There are multiple predominantly ring-enhancing lesions in the bilateral cerebral hemispheres and right cerebellar hemisphere, which are stable to decreased in size. For example, a left anterior cingulate gyrus lesion measures up to 10 mm, previously 13 mm, while a right basal ganglia lesion measures up to 12 mm, previously also 12 mm. In addition, the degree of with associated vasogenic edema has diminished, accounting for differences in technique. The ventricles appear to be similar in size and configuration. There is no midline shift or herniation. The orbits are unremarkable. There is a newly apparent subcentimeter nodule in the apical scalp, perhaps with mild enhancement.
1. The multiple intracranial metastases and associated vasogenic edema are stable to decreased in size, accounting for differences in technique. 2. A newly apparent subcentimeter nodule in the apical scalp is nonspecific, but may represent a metastatic lesion, for example.
