Retroperitoneal bronchogenic cyst masquerading clinically and radiologically as a phaeochromocytoma

Abstract

 Bronchogenic cysts are relatively rare congenital anomalies that represent malformations of the embryonic foregut and are morphologically expressed as maldevelopments of the respiratory system. Anatomically, they can be positioned at any location along the central axis of the respiratory system, but are more commonly discovered in the thorax. Infradiaphragmatic bronchogenic cysts are rare and retroperitoneal ones distinctly unusual. We report a retroperitoneal bronchogenic cyst clinically masquerading as a phaeochromocytoma.
