RT Journal A1 El Youssef R, Fleseriu M, Sheppard BC T1 ADrenal and pancreatic presentation of subdiaphragmatic retroperitoneal bronchogenic cysts JF Archives of Surgery JO Archives of Surgery YR 2010 FD March 1 VO 145 IS 3 SP 302 OP 304 DO 10.1001/archsurg.2010.12 UL http://dx.doi.org/10.1001/archsurg.2010.12 AB Bronchogenic cysts are aberrations of normal development throughout the embryonic foregut; abdominal or retroperitoneal presentations are rare. They will often present a diagnostic dilemma because their appearance can mimic other, more common diagnoses. The initial work-up, differential diagnosis, management, and follow-up may present clinical challenges. We present 1 case of an adrenal lesion and 1 case of a pancreatic lesion that were revealed to be retroperitoneal bronchogenic cysts after surgical extirpation.
