Core tip: Accessory gallbladders are a rare anatomic anomaly, that classically goes unnoticed. These are often not diagnosed preoperatively in patients undergoing cholecystectomy. We present a 27-year-old male scheduled for gallbladder removal for biliary colic. Intraoperatively, following ligation of cystic artery and duct, an additional structure was noted, and intraoperative cholangiogram confirmed a second gallbladder with an associated accessory cystic duct. Pathological analysis confirmed the presence of two gallbladders with features of chronic cholecystitis. Recognizing and understanding the presentation of accessory gallbladders can prevent the pitfalls of surgery with anatomical abnormalities, as well as offering the appropriate management.
