ABDOMEN:LIVER, BILIARY TRACT: No significant abnormality noted.SPLEEN: No significant abnormality noted.PANCREAS: Pancreatic divisum is present.There is a 9 x 7 mm T2 hyperintense focus in the pancreatic head corresponding to that seen on the prior CT. This lesion communicates with the main pancreatic duct, compatible with a side branch IPMN. An additional 5 x 4 mm T2 hyperintense lesion with communication to the main pancreatic duct located closer to the ampulla also likely reflects a side branch IPMN.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: Enlarged right and left cardiophrenic lymph nodes.

1.Pancreatic divisum anatomy. 2.Cystic lesion corresponding to finding reported on prior CT is compatible with a sidebranch IPMN. Additional T2 hyperintense lesion as described above also likely reflects a sidebranch IPMN. Follow-up is recommended to document stability.
