Abstract Background Although annular pancreas concurrent with pancreaticobiliary maljunction has rarely been reported, some reports have pointed out a possibility that both anomalies have a common pathogenesis in pancreatic development. We herein report a case with pancreaticobiliary maljunction diagnosed long after surgical treatment for annular pancreas. Case presentation A 34-year-old female, with a surgical history of duodenal obstruction due to annular pancreas in the neonatal period, was referred to our hospital for further examination of chronic pancreatitis. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed choledocholithiasis, pancreatic lithiasis, and pancreaticobiliary maljunction without biliary dilatation. Choledocholithotomy and cholecystectomy were performed, and highly elevated levels of amylase in bile from the common bile duct were found intraoperatively. Conclusion The present case highlights a possible association of pancreaticobiliary maljunction in a patient with annular pancreas.
