Pheochromocytoma induced cardiomyopathy in a young man: a case report.

Pheochromocytoma is a tumor arising from the adrenal medulla, most frequent benign and, due to the excretion of catecholamines, a rare cause of hypertension. The diagnosis of pheochromocytoma can be challenging because of its episodic nature, unspecific symptoms and rarity. Consequently, treatment can be delayed with serious consequences for the patient. We present a case report regarding a young man with episodes of severe hypertension over a period of at least 9 years. Ultimately, with a possible trigger effect from the intake of multiple energy drinks, the patient presented with severe hypertension, symptoms mimicking acute coronary syndrome, abnormal laboratory parameters and echocardiography suggestive of severe cardiomyopathy. The patient's pheochromocytoma was incidentally identified in a computed tomography scan during the initial workup. Although a rare condition, pheochromocytoma should be considered as a differential diagnosis, especially in young patients presenting with unexplained hypertension, chest pain and cardiac dysfunction.
