摘要
目的探讨胰腺腺泡细胞癌（acinar cell carcinoma of pancreas，ACCP）的cT特征。方法回顾性分析经手术证实的10例ACCP患者资料，患者均行CT平扫加动态增强扫描检查，分析其影像特征。结果肿瘤发生在胰腺钩突4例、胰腺头部1例、胰腺颈部1例、胰腺体部2例、胰尾2例。平均直径6．7cm。直径〉10cm的2例为囊实性肿瘤，其余均为实性。肿瘤边界清晰，无浸润邻近器官、包绕血管表现。增强后动脉期和门静脉期肿瘤强化较周围胰腺弱。所有患者均可见完整或不完整的包膜线状强化。7例对胰（胆）管无明显侵犯；3例引起主胰管扩张，其中1例引起肝内、外胆管扩张。结论ACCP在CT图像上具有特征性表现，有助于疾病的诊断。
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 10cm 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.
