Vomiting in a patient with brain metastases from breast cancer. There are postoperative findings related to right medial cerebellar metastasectomy, with persistent diffuse linear enhancement along the resection cavity and surrounding T2 hyperintensity. There is slight interval decrease in size of a right anterior pons enhancing lesion, measuring up to 11 mm, previously 12 mm. There is slight decrease in size of a medial right occipital lobe lesion, which measures up to 4 mm, previously 5 mm. Likewise, the right corona radiata punctate enhancing and left middle frontal gyrus lesions appear to be slightly smaller. There are postoperative findings in the left anterior frontal lobe with persistent T2 hyperintensity, but no evidence of enhancing lesions. There is scattered cerebral white matter T2 hyperintensity, which is nonspecific. There is no evidence of acute infarct. There is a right frontal lobe developmental venous anomaly. The ventricles and basal cisterns are unchanged 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 unchanged.
1. Postoperative findings related to right medial cerebellar metastasectomy, with persistent diffuse linear enhancement along the resection cavity, which may represent granulation tissue. 2. Slight interval decrease in size of several brain metastases. 3. No evidence of recurrent tumor in the left anterior frontal lobe treatment bed.
