Paragangliomas is a pheochromocytoma of extra adrenal localization. The case report is a male, 55 years old who presented symptoms of adrenergic hyperstimulation associated to an abdominal mass diagnosed as paraganglioma by a biopsy. Because of its size, localization and vascularization, an aortography with embolization of the nutrient branches of the tumor was done pre-operatively. Four days later, a surgical ressection was performed, and the tumor was adhered to the duodenum, infra-renal aorta and inferior vena cava. We believe that an angiographic study pre-operatively with embolization makes possible an analysis of the anastomosis and arterial supplement, making the ressecability of the tumor safer, although it seems the surgical intervention should have been done earlier.
