Female, 73 years old, history of metastatic breast cancer to the brain, surveillance imaging. Again seen are findings related to tumor resection from the right paramedian parietal region. The resection cavity, and T2 hyperintensity surrounding cavity, have not significantly changed from the prior exam. Mild curvilinear enhancement within the resection cavity has decreased in conspicuity from the prior examination. No new areas of suspicious enhancement are seen within or around the treatment bed.Also redemonstrated is a treated left cerebellar lesion which continues to enhance similar to the prior examination. The lesion measures 15 x 10 mm and has not changed in size from the prior study. T2 hyperintensity surrounding this lesion is unchanged as well.No new or concerning areas of intracranial enhancement are identified. An incidental developmental venous anomaly is again seen adjacent to the left cerebellar lesion. A few scattered foci of nonspecific white matter T2 hyperintensity are unchanged. No evidence of significant parenchymal edema or mass effect is detected. The ventricular system is stable and normal in size.
1.Stable appearance of the right paramedian parietal resection bed with no evidence to suggest recurrent or progressive tumor.2.Stable appearance of the treated left cerebellar lesion. The lesion continues to enhance but is unchanged in size.
