Bilateral renal artery stenosis and pheochromocytoma an uncommon association: A case report

Abstract

Pheochromocytoma and bilateral renal artery stenosis have a quite rare association. Although unilateral renal artery stenosis is reported in the literature with Pheochromocytoma but bilateral renal artery stenosis never reported before in Gulf region. A 56-years-old woman primarily referred to our facility for CABG for triple vessel disease but uncontrolled blood pressure and long standing history of hypertension rendered her for further investigations for secondary causes. The technical imaging techniques (USG, abdominal CT, magnetic resonance angiogram (MRA) revealed bilateral renal artery stenosis and left supra-adrenal mass. Further hormonal assays confirmed high catecholamine and raised rennin and aldosterone secondary to Pheochromocytoma and bilateral renal artery stenosis. Laparoscopic removal of Pheochromocytoma with minimum invasive reconstructive surgery for bilateral renal artery stenosis was planned prior to CABG for triple vessel disease but patient declined any surgery or interventional and opted for conservative management inspite of repeated counselling sessions with the patient. Although these conditions co-existed simultaneously but differ in management.
