Although the spontaneous rupture of adrenal pheochromocytoma is rare, it can be lethal because it can induce serious changes in the circulation. We describe a 32 year old man with bilateral pheochromocyroma presenting as abdominal pain. In the emergency room, an abdominal MRI showed an aneurysmal vessel in the right adrenal mass and accompanying hemorrhage around the tumor capsule. The bleeding site was found by transfemoral abdominal angiography. Coil embolization was done in the bleeding vessels, specifically branches of the right adrenal artery. The hemorrhage was successfully controlled and vital signs of the patient were restored. Following emergency care, biochemical and imaging studies showed compatible findings of a bilateral adrenal pheochromocytoma. Postoperative histologic findings confirmed these observations. A ruptured pheochromocytoma should be considered as a cause of acute abdomen in cases of a concomitant adrenal mass. Intratumoral aneurysmal bleeding may be a cause of ruptured tumor, and careful angiographic intervention will help to ensure safe control of bleeding in such an emergency situation, even in cases of bilateral tumor.

Pheochromocytoma is a tumor of the chromaffin cells which secretes catecholamines and 90% of it originates from adrenal medulla. The main symptoms and signs are hypertension, tachycardia, sweating and headache. Rarely, acute abdomen may occur as a result of the rupture of tumoral mass or bleeding inside the mass. Here we present a 43 year old male patient who applied with acute abdominal syndrome and severe hypertension. Abdominal MRI showed a large mass hemorrhagic in nature above the right kidney. At laparotomy, ruptured adrenal mass was seen and excised successfully. The histological evaluation confirmed the diagnosis as pheochromocytoma. Ruptured adrenal pheochromocytoma is a mortal situation potentially and it should be considered in patients who present with an acute abdominal syndrome and hypertension or shock. It should be known that early diagnosis and surgery with proper preoperative treatment is a life saver.
