The rarity of the condition combined with clinical and radiologic features that are indistinguishable from those of more common biliary conditions means that it is rarely diagnosed preoperatively and patients undergo unnecessary operative intervention. Case presentation This case report describes the case of a 79-year-old symptomatic Caucasian man who underwent laparoscopic cholecystectomy for suspected choledocholithiasis despite imaging studies raising suspicion of gallbladder agenesis. Intra-operatively the diagnosis of gallbladder agenesis and associated common bile duct stones was made. Conclusion The preoperative diagnosis of this rare condition is difficult to make. However with advances in biliary tract imaging and with heightened awareness of this anomaly fewer patients will need to undergo unnecessary operative intervention. The authors review the different imaging modalities available to help diagnose this condition and highlight the importance of being aware of this rare anomaly to avoid an operation that carries a high risk of iatrogenic injury. Introduction Isolated agenesis of the gallbladder is a rare congenital anomaly that results from failure of the cystic bud to develop in utero. Since its first description by Lemery in 1701 a number of cases have been published with a reported incidence of to 1 . Patients are usually asymptomatic and the diagnosis is commonly made as an incidental finding during abdominal surgery or at autopsy 2 . It is estimated that 25 to 50 of patients will develop c ommon duct stones at some point and 23 will eventually become symptomatic usually .
