Bronchogenic cyst. A rare differential diagnosis of retroperitoneal tumors

Abstract

Subdiaphragmatic bronchogenic cysts are rare, and those located retroperitoneally are exceptional. A review of the English-language literature revealed only 16 reported cases. We describe an additional case of a retroperitoneal cyst presenting as an asymptomatic adrenal mass and discuss clinical, radiographic, surgical and pathological findings as well as its embryological background.
