79-year-old woman with history of chronic pancreatitis, questionable stone and ventral duct which could not be removed during ERCP on 9/21/2015. ABDOMEN:LIVER, BILIARY TRACT: The liver appears normal. There is no intrahepatic biliary duct dilatation. The gallbladder and common bile ducts appear normal.SPLEEN: The spleen appears normal.PANCREAS: The pancreatic parenchyma is mildly atrophic. No solid masses are identified. Segments of the pancreatic duct are irregularly dilated measuring up to 7 mm in the body. A 20 x 9mm cystic lesion in the pancreatic head (series 8, image 19) appears to communicate with the pancreatic duct. Additionally, there are additional small foci of increased T2 signal which communicated with the pancreatic duct (series 4, images 19 and 20). No pancreatic duct stone is identified.After administration of secretin, a bolus is seen filling the duodenum, however the pancreatic duct does not changed in size.ADRENAL GLANDS: The adrenal glands appear normal.KIDNEYS, URETERS: Subcentimeter T2 hyperintense foci in the kidneys bilaterally are likely cysts. The kidneys are otherwise normal.RETROPERITONEUM, LYMPH NODES: No significant lymphadenopathy noted.BOWEL, MESENTERY: The visualized small bowel and colon appear normal.BONES, SOFT TISSUES: Bilateral Tarlov cysts noted.OTHER: No significant abnormality noted.
1.Irregular pancreatic duct dilatation compatible with given history of chronic pancreatitis.2.Preserved exocrine function but decreased pancreatic duct compliance also compatible with chronic peritonitis.3.Probable side branch IPMN documented in the pancreatic head without suspicious features.4.No obstructing mass or stone identified.
