Peripartum cardiomyopathy has rarely been reported in the presence of pheochromocytoma. We report a case of 18-year-old female, who presented with cardiogenic shock at postpartum period. After extracorporeal membrane oxygenation, her cardiopulmonary function improved. She was diagnosed with peripartum cardiomyopathy, thereafter 24hr urine study and abdomen CT was compatible with pheochromocytoma. The adrenal mass was surgically removed without complications.
