Malignant neoplasm of unspecified site of unspecified female breast [C50.919] / Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: history of brain mets please COMPARE History: NONE Previously seen linear and nodular enhancing lesions on the margin of resection cavity has been significantly decreased but remained focal enhancing area at the anterior lateral aspect of resection cavity. There is no other abnormal enhancing lesion seen on the scan.There is no surrounding edema.Susceptibility artifacts seen on the margin of resection cavity indicate operation related blood product deposition.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Nonvisualization of the most of previously seen resection cavity margin enhancements indicate previous lesions are operation related reactive changes.2. Remained enhancing lesion at the anterior lateral aspect of the resection cavity may represent reactive changes but needs follow up.3. No evidence of acute ischemic or hemorrhagic lesion. No new abnormal enhancement.
