INTRODUCTION: Duplicated gallbladder is a seldom surgical finding that frequently eludes detection on routine preoperative imaging and in some circumstances it might be even overlooked during surgery. Identification of this anomaly and its various types is important in order prevent post operative complications and recurrent symptoms after cholecystectomy. PRESENTATION OF CASE: We present a female patient with biliary simptomatology who had previous cholecystectomy. Preoperatory imaging (MRCP) suspects a duplicated gallbladder which was confirmed intraoperatory and cholecystectomy was performed. The postoperative recovery was uneventful. DISCUSSION: There are a very small number of reported cases with laparoscopic cholecystectomy for overlooked gallbladder duplication. Preoperative diagnosis holds a major contribution in planning surgery and preventing potential biliary injuries or re-operation if accessory gallbladder has been overlooked during initial surgery. CONCLUSION: Accessory gallbladder is a uncommon congenital anomaly that demands particular consideration. Duplicated gallbladder is associated with increased operative difficulty and risks, including conversion to open cholecystectomy common bile duct injury or second cholecystectomy due to overlooked accessory gallbladder
