Synchronous renal oncocytoma and asymptomatic pheochromocytoma. Report of a case

OBJECTIVE: To report a rare case of coexisting renal oncocytoma and pheochromocytoma. To our knowledge, only one such case has been reported in the literature. METHODS: The findings of the imaging studies of this rare case and the unsuspected anatomopathological findings are presented. RESULTS/CONCLUSIONS: Despite its very low frequency, coexisting renal ocnocytoma and pheochromocytoma should be taken into account in patients with synchronous renal and adrenal masses. Unfortunately, there are no radiological patterns that allow us to suspect this rare condition.
