Scintigraphic findings of renal oncocytoma.
Tc-99m DTPA scintigraphy of most renal tumors characteristically discloses a vascular mass, without retention of activity on serial images. Two cases, encountered during hypertensive work-up, are presented with vascular renal masses and persistent DTPA uptake. Oncocytoma was confirmed pathologically in both cases. The authors conclude that renal oncocytomas have a relatively distinctive scintigraphic appearance, which may permit accurate preoperative diagnosis.
