Renal angiography was used historically to evaluate renal tumor arterial anatomy and examine intratumoral vascular patterns, but this modality has largely been supplanted by less morbid and invasive techniques such as CT angiography and magnetic resonance (MR) angiography. A number of typical angiographic signs have been described, including a lucent rim sign, a homogeneous capillary nephrogram phase, the absence of wild neoplastic vessels, and the “spokewheeled” appearance of the feeding arteries [34]. Nevertheless, these features significantly overlap with those observed with RCC, and as a consequence renal angiography cannot be recommended to distinguish between RCC and oncocytoma. | |||

Overview
Intravenous pyelogram may be helpful in the diagnosis of renal oncocytoma.
Other Imaging Findings
Intravenous pyelogram[1]
- Oncocytomas appear as sharply demarcated, often large exophytic masses with enhancement during the nephrographic phase.
