Giant renal oncocytoma: differential diagnosis.
Differentiation between oncocytoma and renal cell carcinoma in preoperative imaging studies remains difficult. We report a huge renal oncocytoma in a 51-year-old male. Despite the characteristic features of this oncocytoma by imaging studies, including a well-defined margin and central stellate scar on computed tomography (CT), and spoke-wheel vascular distribution on angiography, a confident diagnosis of oncocytoma could not be made preoperatively.
