Figure 1 Abdominal magnetic resonance imaging scan and duodenoscopy findings. A: On the coronal magnetic resonance imaging (MRI)/T2-weighted imaging (T2WI), a soft-tissue mass was seen in the middle and upper segments of the common bile duct, as indicated by the orange arrow; B: Magnetic resonance cholangiopancreatography shows a cystic lesion in the pancreatic tail continuous with the main pancreatic duct, as indicated by the orange arrow; C: The axial MRI/T2WI indicates a cystic lesion in the pancreatic tail with visible mural nodules, as indicated by the orange arrow; D and E: Duodenoscopy revealed an enlarged, fish-mouth papilla resulting from excessive mucinous secretion from the bile duct or pancreatic duct-a characteristic endoscopic sign of intraductal papillary mucinous neoplasm or intraductal papillary neoplasm of the bile duct.
