Radiofrequency ablation of multifocal bilateral renal oncocytomas

Abstract

Abstract Renal oncocytoma is a usually benign, typically solitary renal tumor, which cannot be reliably distinguished from other renal neoplasms on the basis of its imaging characteristics. Multifocality and/or bilaterality are very rare; to our knowledge only one case of multiple and/or bilateral oncocytomas is reported in the literature and was treated with partial nephrectomy. We report a case of a 72-year-old patient with multifocal and bilateral renal oncocytomas that were treated with radiofrequency ablation.
