泡型肝包虫病的超声诊断再探讨—附100例分析

Ultrasound Characteristics of Liver Alveococcus (Analysis of 100 Cases)

目的:探讨泡型肝包虫病的B超特征,提出分型依据。方法:综合分析100例经手术或穿刺病理证实的B超声像图表现,并结合部分经CT、MRI检查病例对比研究。结果:100例泡型肝包虫,B超主要表现为①肝内不规则强回声团块80例,其中团块内呈弥漫性粗颗粒状强回声类似"落雪状"改变25例,团块内合并坏死液化20例,团块内钙化25例,钙化和液化同时出现10例。②肝内呈结节状改变20例。结论:泡型肝包虫病表现有其特征性,团块内粗颗粒状强回声,不规则液化坏死,斑片状钙化,周边无低回声暗晕以及彩超团块内无血流信号是与肝癌等肿块鉴别的重要依据。

Objective： To study the ultrasound characteristics of liver alveococcus, according to classification. Methods： The ultrasonographic characteristics of the 100 cases with liver alveococcu confirmed by surgical operation, pathologic examination and GT or MRI, were analyzed. Results： The ultrasonographic characteristics of the 100 cases is as following： 1） 80 showed echogenic area with irregular border, of them ,20 showed central liquefaction , 25 showed calcification , 10 showed both liquefaction and calcification. 2） 20 showed liver nodular. Conclusions. According to the sonograms, the nodes of hepatic alveolar showed intensive echogenicity, scattered calcification,no surrounding dark ring and blood signal; these are identification points between hepatic cancer and hepatic hydatidosis. They are helpful to differential diagnosis.
