Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: S/p SRS for brain metastasis. Surveillance exam. History: S/p SRS for brain metastasis. Surveillance exam. Previously seen right side the enhancing lesion at the junction of right post central sulcus and intraparietal sulcus shows interval decrease in size (which measures about 5.6 mm which was about 8 mm).There is no evidence of another abnormal enhancing lesion.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. 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.Interval decrease of the size of previously seen right postcentral surface and right intraparietal sulcus junctional enhancing lesion since prior scan.2. No other abnormal enhancing lesion is seen.3. No evidence of acute ischemic or hemorrhagic lesion.
