Images obtained during endoscopic retrograde cholangiopancreatography in a 61-year-old patient with steatorrhea, weight loss, and diabetes. The left panel shows an endoscopic image of the papilla, which has a gaping "fisheye" appearance and is exuding mucin. The pancreatogram shows a dilated pancreatic duct and side branches with intraluminal filling defects. The patient underwent a pancreaticoduodenectomy, which confirmed an intraductal papillary mucinous neoplasm.
