Malignant neoplasm of frontal lobe [C71.1], Reason for Study: ^Reason: preop planning for tumor resection History: preop planning. Multiple fiducial markers attached on scalp.Previously demonstrated left frontal lobe nodular enhancing lesions as well as T2 high signal intensity lesions are again seen, unchanged since prior scan. The ventricles, sulci and cisterns are unchanged. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Preoperative localization MR shows unchanged left frontal lobe high T2 signal lesion with multiple nodular enhancing lesions, unchanged since prior scan.
