She received a contrast computed tomography scan of the abdomen which revealed a retroperitoneal cystic lesion below the left crura of diaphragm. Afterward, the patient underwent a laparoscopic excision of the cystic lesion and was discharged uneventfully at postoperative day 4. Histopathological findings confirmed the diagnosis of retroperitoneal bronchogenic cyst. Our literature review identified 55 adult cases in recent two decades. The average age at diagnosis was 43.2 (range 17\u201369) years. 44 (80%) cases had a retroperitoneal cyst on the left side, and 52 (94.5%) cases underwent curative excision through open or laparoscopic surgery.
