History of pancreatic ductal dilatation on endoscopic ultrasound without an obvious mass. Ampullary biopsy showed no mass. ABDOMEN:LIVER, BILIARY TRACT: Few scattered probable cysts. No focal lesion. Normally distended gallbladder. No intrahepatic biliary ductal dilatation. Mild prominence of the common bile duct to the level of the ampulla without a discrete lesion within the limitations of a nonenhanced study.SPLEEN: No significant abnormality noted.PANCREAS: Significant main pancreatic ductal dilatation up to 7 mm involving the pancreatic head and body with smooth tapering distally without pancreatic parenchymal atrophy or mural nodularity. Accounting for differences in technique the overall appearance is similar to the 6/15/2012 study.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: The kidneys are atrophic with the parenchyma replaced with numerous hyperintense cysts reflecting acquired cystic kidney disease of dialysis. Evaluation is limited without contrast however no suspicious lesion is evident.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.Main pancreatic ductal dilatation which tapers distally without pancreatic atrophy or mural nodularity. Although evaluation is limited without contrast there is no discrete lesion evident. The overall appearance is similar to the 2012 CT accounting for differences in technique.2.Acquired cystic kidney disease with limited nonenhanced evaluation showing no suspicious lesion.
