Summary Pheochromocytoma commonly presents with symptoms and signs of catecholamine excess,such as hypertension,tachycardia and headache.Cardiovascular manifestations include catecholamine-induced cardiomyopathy,which may present as severe left ventricular dysfunction and congestive heart failure.Glucocorticoids have been reported to carry an increased risk of catecholaminergic crisis in patients with pheochromocytoma.We report a case of a 37-year-old female,who presented with features of pheochromocytoma induced cardiomyopathy with severe left ventricular dysfunction following glucocorticoid administration.We highlight the dramatic symptomatic improvement and reversal of cardiomyopathy.
