History of dilated pancreatic duct with question of main duct pancreatic mucinous neoplasm. History of ulcerative colitis. ABDOMEN:LIVER, BILIARY TRACT: Cholelithiasis within a normally distended gallbladder without acute inflammatory changes.Mild steatosis.The liver is normal morphology and size without a focal suspicious lesion. No intra or extrahepatic biliary ductal dilatation. The vessels are patent.SPLEEN: The spleen is normal in size and signal intensity.PANCREAS: Demonstrated again is marked smooth main pancreatic ductal dilatation up to 11 mm. There is side branch ectasia.The main pancreatic duct appears to cross the common bile duct and drain into the minor papilla. There is no suspicious mural postcontrast enhancement.Following secretin administration there appears to be adequate exocrine response of the pancreas without significant caliber change of the main pancreatic duct.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Left renal simple appearing cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Mild scoliosis.OTHER: No significant abnormality noted.
Demonstrated again is significant smooth main pancreatic ductal dilatation without suspicious postcontrast enhancement, remaining suspicious for main duct IPMN. No obstructing masslesion or stone. Sequela of chronic pancreatitis felt to be less likely given absence of characteristic alternating pancreatic ductal stenosis/dilatation.Suspected pancreas divisum.
