Pheochromocytoma and fibromuscular hyperplasia

We have described a case which documents two possible surgical correctable causes for hypertension in a 55-year-old white man. Preoperative renal arteriograms and renal vein renin determinations suggested the possibility of renal artery stenosis due to fibromuscular hyperplasia. At operation, a pheochromocytoma was found in the left suprarenal area. The presence of two unusual causes for hypertension in a single patient suggests that more than one remediable cause of hypertension should at least be considered in a given hypertensive patient.
