title: Benign non-parenchymal renal tumors: radiologic appearances.
abstract: Two non-parenchymal renal tumors, capsular leiomyoblastoma and schwannoma in renal sinus, are reported with respect to radiographic appearance, reviewing the literature. Computerized tomography (CT) scan and pyelography define the localization of the renal tumor substantiated by angiography identifying the feeding arteries. Precise investigation of neovascularity is necessary to exclude malignant potency. A tumor in the renal sinus without destruction of pelvo-calyceal system should include schwannoma in the differential diagnosis.
