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
