History of multiple pancreatic cysts. Evaluate for suspicious imaging characteristics. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology and size, measuring 15 cm in craniocaudal dimension. No focal suspicious lesion, biliary ductal dilatation or vascular abnormality.SPLEEN: The spleen is normal in size without a focal lesion.PANCREAS: The pancreas is mildly atrophic. It is normal in signal intensity. The main pancreatic duct appears to drain into the major papilla. There is an additional dilated tubular structure in the pancreatic head/uncinate process (series 9/23) which appears to drain into the major papilla, slightly more prominent than previously but seen dating back to 2008. This may represent a dilated side-branch versus variant ductal anatomy. Several subcentimeter cystic lesions are noted in the pancreas parenchyma the largest being in the body measuring 9 x 6 mm (series 10/15), essentially unchanged. It appears to communicate with a normal caliber main pancreatic duct.No suspicious enhancement characteristics.Additional subcentimeter cystic pancreatic foci are too small to characterize, unchanged.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Stable small cystic pancreatic body lesion likely represents a sidebranch IPMN without suspicious imaging characteristics.2. Dilated side-branch versus variant ductal anatomy appearing essentially unchanged dating back to 2008.
