ABSTRACT
Pheochromocytomas are catecholamine-producing tumors and a rare cause of sudden cardiac death. We describe the case of a previously healthy 28-year-old man who presented after a ventricular fibrillation out-of-hospital cardiac arrest (OHCA). His clinical investigation, including a coronary evaluation, was unremarkable. A protocolized head-to-pelvis computed tomography (CT) scan was ordered and revealed a large right adrenal mass with subsequent laboratory studies showing markedly elevated urine and plasma catecholamines. This raised suspicion for a pheochromocytoma as the underlying etiology behind his OHCA. He received appropriate medical management, underwent adrenalectomy with subsequent normalization of his metanephrines, and fortunately did not have recurrent arrythmias. This case highlights the first documented case of a ventricular fibrillation arrest as the initial presentation of pheochromocytoma crisis in a previously healthy individual, and how the use of early protocolized sudden death CT scan allowed for the prompt diagnosis and management of a rare cause of OHCA. Learning objective:
We review the typical cardiac manifestations of pheochromocytoma and describe the first case of a pheochromocytoma crisis presenting as sudden cardiac death (SCD) in a previously asymptomatic individual. In young patients with unexplained SCD, it is important to consider pheochromocytoma in the differential diagnosis. We also review why an early head-to-pelvis sudden death computed tomography scan protocol may be helpful in the evaluation of patients resuscitated from SCD without an obvious etiology.
