Renal oncocytomas are uncommon, benign tumors that can be treated by local incision or heminephrectomy; their preoperative differentiation from renal cell carcinoma, treated by radical nephrectomy, would be invaluable. A particularly important finding, a central scar, not stressed in previous reports, is frequently demonstrated by CT examination. The authors evaluated radiographic studies of 18 pathologically confirmed cases of oncocytoma and compared findings with results of CT, sonography, and angiogrpahy studies of 18 renal cell carcinoma cases. Oncocytomas can be suggested if a stellate scar is identified within an otherwise homogeneous tumor on ultrasound (US) and CT; if the mass appears homogeneous but no scar is present, angiography should be performed.
