Overview
Renal angiography may be helpful in the diagnosis of renal oncocytoma. The “spoke-wheeled” appearance, lucent rim sign, homogeneous capillary flush in the nephrogram phase, lack of wild neoplastic vessels,and both hypovascular or hypervascular may seen on angiography of patients with renal oncocytoma. Although, none of them are specific for renal oncocytoma and they also may seen in RCCs.
Other Imaging Findings
Renal angiography
Renal angiography may be helpful in the diagnosis of renal oncocytoma.
Findings on an angiography which are suggestive of renal oncocytoma include:[1][2][3][4][5][6]
- The “spoke-wheeled” appearance which is developed from the radiation of feeding arteries toward the lesion's center
- Lucent rim sign
- Homogeneous capillary flush in the nephrogram phase
- The lack of wild neoplastic vessels
- Both hypovascular or hypervascular may be seen on angiography
Note: None of these characteristics are specific for renal oncocytoma and they also may seen in RCCs.
