Malignant neoplasm of unspecified site of unspecified female breast [C50.919] / Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: Hx: metastatic breast cancer to the brain. Compare to prior MRI for brain mets, s/p WBRT The enhancing lesion located at slightly right side of anterior aspect of pons is again seen, unchanged in terms of size, and MR characteristics since prior scan.Relatively thick linear enhancement along the resection cavity of the right cerebellar hemisphere as well as T2/FLAIR high signal intensity lesions on the left frontal lobe and the right frontal lobe are again seen, unchanged.Nodular enhancing lesion on the right anterior aspect of occipital lobe does not show any significant interval change since prior scan.The ventricles, sulci and cisterns are unremarkable. There is no midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. 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. Unchanged pontine and right occipital lobe enhancing lesions since prior scan.2. Unchanged relatively thick linear enhancing lesions of the right cerebellar resection cavity since prior scan.3. Unchanged bilateral frontal T2/FLAIR high signal intensity lesions since prior scan.4. No evidence of new abnormal enhancing lesion.5. No evidence of acute ischemic or hemorrhagic lesion.
