Renal cancer with questionable base of skull lesion on CT. The sella and pituitary gland appears to be grossly unremarkable. There is fatty bone marrow within the clivus, which is normal. There is diffuse patchy cerebral and pontine white matter T2 hyperintensity. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is susceptibility artifact related to metal in the skin overlying the right frontal process of the maxilla that obscures surrounding structures.
1. No evidence of pituitary or central skull base lesions, within the limitations of non-contrast technique.2. Diffuse patchy cerebral and pontine white matter T2 hyperintensity may be related to chronic small vessel ischemic disease.
