Bronchogenic cysts is commonly defined as rare neoplasm entity and solely few cases have been reported in literature. Commonly found in the posterior pocket of the mediastinum, the bronchogenic neoplasm could be unusually found in subdiaphragmatic zones, as our reported retroperitoneal site. Our paper reports a case of retropancreatic bronchogenic cyst in a 32 year old man, with negative previous medical history and clinically silent case. Differential diagnosis need to be considered during the assessment of abdominal diseases and consequently abdominal ultrasound, MRi and CT scans are the best imaging modalities, being really helpful during the clinical approach. We used firstly abdominal ultrasound and fine needle aspiration to nearly secure the diagnosis and after a MRi abdominal scan as a secondly diagnostic step. Subsequently our patient underwent a laparoscopic approach of the distal pancreatic gland portion associated with spleen preserving technique, followed by intact detaching of the cystic lesion from the retroperitoneal area, using electrocauterization and Harmonic scalpel, believing that it was the only recommended way to establish the diagnosis. Lastly postoperative histopathological report defined it as to be bronchogenic in origin. The postoperative recovery days were uneventful with a rapid and asymptomatic discharge on day 8; on follow-up controls were made as clinical observations and were without concerns.
