Malignant neoplasm of right renal pelvis [C65.1], Reason for Study: ^Reason: kidney cancer with new headaches; r/o metastases History: headaches No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.Scattered multifocal somewhat patchy FLAIR high signal intensity lesions on bilateral periventricular white matter and centrum semiovale indicate nonspecific small vessel ischemic disease.There is a focal tissue loss on the left cerebellar hemisphere at the level of middle cerebellar peduncle indicate focal encephalomalacia.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.
1. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement.2. Non specific small vessel ischemic disease.3. Focal tissue loss on the left cerebellar hemisphere likely indicate chronic ischemic infarction.
