摘要

目的：

探讨肝内胆管癌（intrahepatic cholangiocarcinoma，ICC）与肝脏炎性假瘤（inflammatory pseudotumor，IPT）的超声造影（contrast-enhanced ultrasound，CEUS）鉴别要点。

方法：

分析50例ICC病灶和45例IPT病灶的血清学肿瘤标志物、常规超声及CEUS图像，探讨两种病变的鉴别诊断特征。

结果：

血清学肿瘤标志物中，糖类抗原19-9（carbohydrate antigen 19-9，CA19-9）升高在两组间差异有统计学意义（

＜0.05）；常规超声中，病灶内部回声均匀性、内部有无血流信号及周边有无胆管扩张在两组间差异有统计学意义（

＜0.05）；CEUS中，动态增强模式快进快退在两组间差异有统计学意义（

＜0.05）；动脉期病灶呈三种增强方式：周边环状增强、整体不均匀增强和整体均匀增强，两组间增强方式差异有统计学意义（

＜0.05）。

结论：

CEUS对ICC与IPT的鉴别诊断可提供更多的信息，具有一定的应用价值。

Abstract

Objective:

To investigate the differential features between intrahepatic cholangiocarcinoma (ICC) and hepatic inflammatory pseudotumor (IPT) by contrast-enhanced ultrasound (CEUS).

Methods:

The serum tumor maker

conventional ultrasound and CEUS images of 50 ICC lesions and 45 IPT lesions were analyzed

and the the differential diagnostic features of them were discussed.

Results:

There were significant differences in the increase o

f carbohydrate antigen 19-9 (CA19-9) between the two groups (

＜0.05). The conventional ultrasound features

including homogeneity of internal echo

blood flow signal and biliary dilatation

were statistically significant between the two groups (

＜0.05). Enhanced contrast dynamic mode

rapid hyperenhancement in the arterial phase and rapid wash out was significant differences between the two groups (

＜0.05). There were three modes of enhancement in the arterial phase of lesions: peripheral ring enhancement

global heterogeneous enhancement and global homogeneous enhancement

and the difference in enhancement modes between the two groups was statistically significant (

＜0.05).

Conclusion:

CEUS can provide more information for differential diagnosis of ICC and IPT lesions

which has certain diagnostic value.
