Secondary malignant neoplasm of brain and spinal cord(198.3) [198.3], Reason for Study: ^Reason: Eval brain mets. History: Hx CVAs. NSCLC. Redemonstration of left frontal lobe encephalomalacia seen of with the susceptibility artifacts indicating prior hemorrhage is lesion, no change since prior scan.There is a focal lacunar infarct on the left thalamus, no change since prior scan.There is no evidence of abnormal enhancement.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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.
No change of left frontal lobe chronic hemorrhagic lesion with encephalomalacia since prior scan.No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.
