Acute abdominal symptoms caused by hemorrhagic necrosis of a pheochromocytoma: Report of a case

Abstract

The diagnosis of pheochromocytoma is often difficult in a patient presenting with acute illness but without the classical constitutional symptoms. We report herein the case of a woman who developed acute abdominal symptoms following hemorrhagic necrosis of a previously unsuspected pheochromocytoma. This patient underwent successful emergency resuscitation followed later by elective surgical resection of a right adrenal pheochromocytoma. A review of 27 other cases indicates that a fatal outcome is likely to result without the initiation of prompt and appropriate emergency treatment, followed later by removal of the tumor. Thus, early diagnosis is important not only for controlling hypertension, but also because performing a laparotomy on a patient with unrecognized hemorrhagic necrosis of pheochromocytoma can create a potentially lethal situation.
