We describe a patient with pheochromocytoma who developed noncardiogenic pulmonary edema, shock and multiorgan failure after a hypertensive crisis. The low levels of catecholamines and the hemodynamic response to administration of labetalol and adrenaline suggest an exhaustation of adrenal function after << catecholamine storm >>. After a glucagon test, we found electrocardiographic alterations of catecholamine-induced myocarditis.
