Secondary malignant neoplasm of brain [C79.31] / Secondary malignant neoplasm of other parts of nervous system [C79.49], Reason for Study: ^Reason: metastatic lung cancer to brain s/p SRS History: surveillance There are multifocal minimally enhancing intra axial lesions including left frontal lobe, left cerebellar hemisphere, right superior parietal lobule, left intraparietal sulcus and right occipital cortex, no change in terms of size and enhancement pattern and other MR imaging findings.The left frontal lobe and left cerebellar hemisphere lesions show susceptibility artifacts indicating internal development of hemorrhage, unchanged.The ventricles, sulci and cisterns are unremarkable. The gray-white matter differentiation is normal. There is no restricted diffusion/acute ischemia. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.Minimal tonsilar downward displacement is again seen.
1. Multiple minimally enhancing intra axial lesions consistent with metastatic lesions, unchanged in terms of size, number and MR findings since prior scan.2. No new enhancing lesion is seen.3. No evidence of new acute ischemic or hemorrhagic lesion.
