Bilateral Renal Artery Stenosis With a Pheochromocytoma

Renal artery stenosis (RAS) is a common cause of secondary hypertension. Pheochromocytomas have been associated with hypertension in 0.1% of the population. Pheochromocytoma is a well-documented co-morbid condition of unilateral RAS. Bilateral RAS with a pheochromocytoma is extremely rare with only one documented case in the literature. We present the second documented case of bilateral RAS with a pheochromocytoma. The coexistence of these pathologies makes diagnosis challenging. Proper diagnosis of the etiology of hypertension is essential given the pre-surgical treatment required for neuroendocrine tumors.
