Recurrent ventricular tachycardia as initial presentation of pheochromocytoma: A case report and literature review

Abstract

Pheochromocytoma is a neuroendocrine tumor of the adrenal gland that secretes excess amount of catecholamine, which in turn leads to extremely varied clinical manifestations, such as hypertension, headache, sweating and palpitations. This eventually leads to delay or mistakes in diagnosing the disease. This could be fatal due to misdiagnosis as it receives a totally different treatment. We herein reported a case of pheochromocytoma with recurrent ventricular tachycardia. A literature review was conducted to investigate the clinical features of these patients.
