Secondary malignant neoplasm of brain [C79.31] / Secondary malignant neoplasm of other parts of nervous system [C79.49], Reason for Study: ^Reason: 3 t scanner recurrent brain tumor Limited sequence exam for pre-surgical localization.Redemonstration of enhancing lesions on the right precentral gyus and left cerebellar lesion, unchanged since prior scan.There is no evidence of new enhancing lesion on this scan.Diffuse bihemispheric dural enhancement, left occipital approach catheter, right middle cranial fossa artifacts, right frontal metallic artifacts and left frontal burr hole are again seen, unchanged since prior scan.The ventricles, sulci and cisterns are unremarkable. The midline structures and cranial-cervical junction are unremarkable. The paranasal sinuses and mastoid air cells are clear.
