Intraperitoneal bronchogenic cysts are an extremely rare entity. We herein present a case of a lesser sac bronchogenic cyst originally detected prenatally intra-abdominal cyst. The cyst gradually increased in size and laparoscopic resection of the cyst was successfully performed when the patient was 3 years of age. Reduced port surgery was performed, with good cosmetic results. Only eight children with bronchogenic cysts in abdominal lesions have previously been reported and this is the first report of laparoscopic reduced port surgery for the treatment of an abdominal bronchogenic cyst. After presenting this case, we also review the pertinent literature.
