摘要

背景与目的：胰腺腺泡细胞癌(acinar cell carcinoma of the pancreas，ACCP)是一种罕见的胰腺恶性肿瘤，相关的影像学报道较少。该研究旨在探讨ACCP的CT表现。方法：收集自2011年1月—2014年1月经手术病理证实为ACCP的9例患者资料，回顾性分析其CT征象。结果：在9例ACCP患者中，肿块最大径均值为52 mm，肿瘤边缘不清的6例(66.7%)，外生型生长者有6例(66.7%)，强化程度低于正常胰腺组织者8例(88.9%)，强化不均者6例(66.7%)，累及血管者7例(77.8%)，淋巴结转移者5例(55.6%)，无出现肝转移病例，仅1例出现胰管扩张。结论：较大体积的乏血供胰腺肿块，内部异质性明显，呈外生型生长而无显著胰管扩张时，提示ACCP的可能。

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.
