Abstract:
Objective To assess CT characteristics of acinar cell carcinoma of pancreas(ACCP).Methods Ten patients (9 males,1 female,median age 62 years ) with ACCP proved histopathologically were collected during January 2001 to August 2010.The unenhanced and contrast-enhanced CT were performed in all patients.Results The tumors were distributed in the uncinate ( n =4 ),head ( n =1 ),neck ( n =1 ),body ( n =2 ),and tail ( n =2 ) of pancreas.The average tumor size is 6.7 cm( range 2.0 to 15.0 cm).Two patients whose size over 10 cm were solid-cystic tumors,the rest were solid. All patients demonstrated a defined border,no-infiltrate to surround organs and blood vessels.The tumors enhanced less than adjacent normal pancreatic parenchyma in arterial phase and portal venous phase.All patients could be seen uniform and partial thin and enhancing capsules.Seven patients had no influence on pancreatic (bile) tube.Three patients caused the main pancreatic duct to expansion,one patients caused intrahepatic and extrahepatic bile ducts to expansion. Conclusion ACCP has distinct characteristics in CT and these characteristics are related to its histopathology findings.
