Pheochromocytoma, a rare catecholamine-secreting tumor, typically manifests itself with paroxysmal hypertension, tachycardia, headache, and diaphoresis. Less often, symptoms related to substantial hemodynamic compromise and cardiogenic shock occur. We report the case of a 66-year-old woman who presented with abdominal pain. Examination revealed a large right adrenal mass, cardiogenic shock, and severe heart failure in the presence of normal coronary arteries. Within days, the patient's hemodynamic status and left ventricular ejection fraction improved markedly. Results of imaging and biochemical tests confirmed the diagnosis of pheochromocytoma-induced takotsubo cardiomyopathy. Medical therapy and right adrenalectomy resolved the patient's heart failure, and she was asymptomatic postoperatively. We recommend awareness of the link between pheochromocytoma and takotsubo cardiomyopathy, and we discuss relevant diagnostic and management principles.
