Laparoscopic resection of retroperitoneal bronchogenic cyst clinically presenting like adrenal cyst.

Bronchogenic cyst that is localized to retroperitoneum is a rare clinical entity. It is a congenital malformation generally occuring in the posterior mediastinum due to abnormal development of the foregut. We report the case of a retroperitoneal cyst presented like left adrenal cyst. A 38 years old female was presented with left upper abdominal pain. Endocrinologic evaluation was done and no adrenal hormonal secretion was detected. The cyst was removed laparoscopically. It was confirmed in pathologic examination as a bronchogenic cyst. Bronchogenic cysts should be considered in the differential diagnosis of retroperitonal cysts. Laparoscopic resection of retroperitoneal cysts results in better outcome.
