CT characteristics of acinar cell carcinoma of the pancreas

doi:10.3969/j.issn.1007-3969.2016.03.012

Abstract

Abstract: Background and purpose: Acinar cell carcinoma of the pancreas (ACCP) is a rare malignant tumor and a few radiologic reports have been published. This study aimed to evaluate the CT characteristics of ACCP. Methods: CT signs of 9 cases of pathologically confirmed ACCP were analyzed retrospectively. Results: The mean value of longest diameter of the 9 cases of ACCP was 52 mm. Among the 9 cases, 6 cases (66.7%) had ill-defined border, 6 cases (66.7%) showed exophytic type, 8 cases (88.9%) showed enhancement degree less than normal pancreatic tissue, 6 cases (66.7%) represented heterogeneous enhancement, 7 cases (77.8%) showed invaded vessel, 5 cases (55.6%) had lymph node metastasis, and none had hepatic metastasis. Dilated pancreatic duct was observed in only 1 case. Conclusion: When pancreatic mass is large, heterogeneous, exophytic and without dilated pancreatic duct, ACCP is suggested.
