Overview

Renal MRI may be helpful in the diagnosis of renal oncocytoma. Findings on MRI suggestive of renal oncocytoma include central scar, satellite pattern, pseudo-capsule, hypointensity in T1 and hyperintensity in T2 weighted images. Although, none of these characteristics can differentiate between renal oncocytoma and renal cell carcinoma (RCC).

MRI

MRI may be helpful in the diagnosis of renal oncocytoma. Findings on MRI suggestive of renal oncocytoma include:[1][2][3][4][5][6][7]

Note: None of these characteristics can differentiate between renal oncocytoma and RCC.
