Background: Bronchogenic cysts (BC) are developmental anomalies derived from foregut, most commonly found in mediastinum but rarely in retroperitoneum. Very few cases have been reported in the literature. Most BCs are asymptomatic and are identified incidentally during imaging done for unrelated reasons. Surgical exploration is recommended. Very few cases of laparoscopic resection of the cyst have been reported.
Case Presentation: We present a case of 73 year old female patient who was found to have left retroperitoneal cyst on MRI during workup for chronic flank pain. Patient underwent Endoscopic Ultrasound (EUS) as further work up to further define the lesion. Laparoscopic fenestration of the cyst was performed. Pathology showed benign bronchial-type epithelial cells with focal adrenal tissue.
Conclusion: Bronchogenic cysts are extremely uncommon anomalies that are mostly asymptomatic and diagnosed on imaging studies done for unrelated reasons. Most of these are benign cysts. Surgical exploration is recommended. Laparoscopic fenestration is safe and feasible management approach.
