We present the case of a 60-year-old woman admitted to hospital with acute abdominal pain on a background history of vague dyspeptic symptoms managed as an outpatient. Serial imaging investigation with a barium contrast meal, oesophagogastroduodenoscopy, ultrasonography, computed tomography, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography (MRCP) established a very rare diagnosis. Our patient had extrahepatic bile duct duplication with an accessory bile duct draining the left lobe of the liver into the antrum of the stomach without intrahepatic communication of the left and right bile duct systems, complicated by choledocholithiasis of the accessory duct. Diagnosis of this variant was finally made with MRCP at 2 months follow-up to the initial admission, which also demonstrated spontaneous passage of the accessory duct stone. A differential diagnosis list for cystic structures in the lesser omentum is considered. We believe that this is the first such case to be demonstrated with all 6 forms of imaging described, which were performed, undoubtedly, because of its rarity. Retaining awareness of such rare anomalies in our clinical practice should lead to appropriate imaging being initiated early and avoid delay in diagnosis, especially because of associations with potentially serious complications.
