Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: metastatic NSCLC with brain mets, s/p SRS, assess for recurrence/progression History: post-treatment follow-up Previously seen enhancing lesions including right inferior parietal lobule, left post central gyrus and left temporo-occipital (only seen on fat saturated axial scan, series 10, image #20/32) lesions appear to be stable in size and enhancement degree since prior scan.There is no other abnormal enhancing lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. 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. Stable multiple enhancing lesions in terms of size, enhancement degree and pattern since prior scan.2. No evidence of new abnormal enhancement. No acute ischemic or hemorrhagic lesion.
