History of hypodense pancreatic head mass. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology size and signal intensity. Scattered small subcentimeter cysts. No focal suspicious lesion. The vessels are patent. No biliary ductal dilatation. Normally distended gallbladder without gallstones.SPLEEN: The spleen is normal in morphology and size.PANCREAS: The pancreas is normal in morphology without parenchymal atrophy. The main pancreatic duct is normal in caliber and inserts into the major ampulla. It demonstrates a looped morphology, a normal variant. No focal suspicious lesion.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Bilateral renal cysts. No hydronephrosis.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.
No discernible discrete lesion is evident at the level of the ampulla as described on the recent CT. This is felt to likely represent a normal ampulla given the lack of upstream biliary and pancreatic ductal dilatation as well as no corresponding restricted diffusion.
