    Abstract:
    An unusual case of pheochromocytoma associated with renal artery stenosis is described. Despite the removal of bilateral adrenal pheochromocytoma, laboratory findings suggested the presence of residual pheochromocytoma and abdominal aortography revealed more pronounced stenosis of the right renal artery. Two months later, the undetected residual pheochromocytoma underwent hemorrhagic necrosis with acute cessation of catecholamine release. Thereafter, the patient's blood pressure decreased to a normal level with marked improvement in hypertensive symptoms. No remaining stenosis was demonstrated on follow up renal angiography. Our case suggests that constant local secretion of catecholamines may be responsible for the development of renal artery stenosis.
