A 52 year old woman had an incidental finding of a 4 cm left para aortic mass. Evaluation revealed elevation of urinary metanephrines, normal cortisol and aldosterone levels. MIBG scan confirmed uptake in the mass only. CT guided biopsy confirmed presence of neuroendocrine tumor. Patient had occasional headaches and her blood pressure was normal. She was treated with phenoxybenzamine in preparation for resection of the tumor. Laparoscopic resection was successful. The mass was approached transperitonealy through the left colon mesentery. The tumor originated from the organ of Zuckerkandl in close proximity to the inferior mesenteric artery and the left ureter. The patient was discharged the next day. Pathology confirmed neuroendocrine tumor. We have resected two other extraadrenal paragangliomas successfully previously. Extraadrenal paraganglionomas are rare. They are more likely to be maligant and to recur than adrenal pheochromocytomas. Laparoscopic resection is feasible but more difficult than adrenal tumors, because of paragangliomas have multiple feeding vessels.
