Key result
Adrenalectomy after phenoxybenzamine pretreatment yields full recovery in a young male with pheochromocytoma-induced cardiogenic shock.
Case Report (n=1)
Pheochromocytoma should be considered early in the differential diagnosis of patients presenting with unexplained cardiovascular compromise, such as acute heart failure and cardiogenic shock.
Supports considering pheochromocytoma in unexplained cardiogenic shock; leaves open generalizability of this single-case management approach.
Pheochromocytoma is an endocrine tumor classically presenting with headache, paroxysmal hypertension, and palpitations. We discuss the case of a young male, presenting with acute heart failure and cardiogenic shock requiring stabilization with an intra-aortic balloon pump and a combination of ionotropes and vasopressors. Pheochromocytoma was diagnosed by CT scan, as well as urine and plasma metanephrines. After pretreatment with phenoxy-benzamine, the patient underwent adrenalectomy with subsequent cardiovascular stabilization and full recovery. Unfortunately, pheochromocytoma often remains undiagnosed. Given the ample diagnostic tools and good prognosis when treated suitably, the diagnosis should be entertained early in patients, presenting with unexplained cardiovascular compromise.

Steppan et al. (2011) conducted a case report in Pheochromocytoma presenting as acute heart failure and cardiogenic shock (n=1). Adrenalectomy after pretreatment with phenoxy-benzamine was evaluated on Cardiovascular stabilization and full recovery. Adrenalectomy after pretreatment with phenoxy-benzamine led to cardiovascular stabilization and full recovery in a young male with pheochromocytoma presenting as cardiogenic shock.
