Abstract
Pheochromocytoma is a neuroendocrine tumor arising from the adrenal medulla, which often causes an adrenalin rush in the treating surgeon and the anesthesiologist. The tumor rupture presenting as acute abdomen and shock is a rare and life-threatening event. We present a case report of ruptured metastatic pheochromocytoma in a 37-year-old patient whose signs and symptoms included acute abdomen and shock. The exact mechanism causing the spontaneous rupture of a tumor is not clearly understood although some theories are proposed. CT scan is the most important investigation in this emergency. A high index of suspicion is needed to diagnose rupture in a known case of pheochromocytoma presenting with acute abdomen and shock. Ruptured pheochromocytoma is a rare emergency, and timely and precise diagnosis and initial primary nonsurgical approach followed by elective surgical resection are to be practiced whenever possible. When emergency exploration is imminent, a multi-specialty team should be prepared with a well-equipped ICU, rapid hemodynamic monitoring and corrections, massive blood transfusion protocol, and timely resuscitation.
