摘要
目的 探讨肝泡性包虫病在B超、CT和磁共振成像 (MRI)影像学检查中的图像特征 ,以提高术前诊断率。方法 收集 1984年 1月至 2 0 0 0年 12月经手术治疗的 4 6例肝泡性包虫病患者的术前影像学检查资料 (均行B超和CT检查 ,12例行MRI检查 ) ,对照手术病理所见进行分析。结果基于泡球蚴的基本病理形态、组织结构与病程发展演变的特殊影像学征象 ,可归纳为病灶浸润 (41例 ,89 1% )、钙化 (39例 ,84 8% )、液化空洞 (37例 ,80 4 % ) 3种类型 ,这 3种类型可以并存。在 3种类型中共发现 9项具有特异性诊断意义的图像特征 ,即晕带征、钙化征、年轮征、内陷征、空腔征、岩洞征、半岛征、小泡征与地图征。结论 肝泡性包虫病具有特异性影像学征象 ,在 9项具有特异性诊断意义的图像特征中 ,只要确认其中 1项 ,即可确诊。
Objective To study the characteristics of hepatic alveolar echinococcosis in B mode ultrasonography (BU), computerized tomography (CT), and magnetic resonance imaging (MRI) so as to increase the pre operative diagnostic rate. Methods The data of forty six cases with hepatic alveolar echinococcosis who underwent operation during the period January 1984 to December 2000 were analyzed and compared with the patholoigical findings of the resected specimens. All of the cases were examined by BU and CT, and 12 of them were examined by MIR. Results The imaging charateristics of the 46 cases were divided into three types: infiltration (41 cases, 89.1%), calcification (39 cases, 84.8%), and cavity with liqueficaction (37 cases, 80 4%). Nine imaging signs were found to be specific to hepatic alveolar ecchinococcosis and of diagnostic significance: halo belt sign, calcification sign, annual ring sign, invacuation sign, cavity with liqueficaction sign, grotto sign, peninsula sign, alveolar sign. With these signs, the diagnostic accuracy rate reached 97.7% in this series. Conclusion There are nine imaging diagnostic signs specific to hepatic alveolar ecchinococcosis. They help detect the location, pathology of this disease and determine operation program. Identification of only one of them is adequate for diagnosis of hepatic alveolar echinococcosis.
