Pheochromocytomas are rare catecholamine-secreting neuroendocrine tumors. Their episodic nature is correlated with abrupt catecholamine release and clinical manifestations that mimic other vascular conditions, leading to delayed diagnosis and potentially life-threatening complications, such as acute myocarditis and pheochromocytoma crises. In this report, we described the case of fulminant adrenergic myocarditis-induced cardiogenic shock requiring extracorporeal membrane oxygenation support in a Vietnamese middle-aged man with a 5-year history of Brugada syndrome, hypertension, and previously undiagnosed pheochromocytoma. After stabilization, the patient was medically treated with a combination of α- and β-blockers before undergoing laparoscopic right adrenalectomy.
Keywords: Brugada syndrome; fulminant adrenergic myocarditis; pheochromocytoma; pheochromocytoma crisis.
