肝囊性包虫病的影像学诊断与分型

目的：探讨肝囊性包虫病在不同影像学检查中的图像特征和影像学诊断分型。方法：收集1984年1月至2000年12月经手术治疗的2039例肝囊性包虫病患者术前B超,CT（909例）和磁共振成像（MR1,24例）检查资料,对照手术病理所见进行分析。结果：影像学检查不仅可检测出包虫寄生部位,类型,大小及性状,并能显示出各种并发症病理形态改变的典型图像,影像学诊断可划分为7型,即单发型（1625例,79．70％）,多发型（414例,20．30％）,子囊型（1114例,54．63％）,钙化型（186例,9．12％）,实变型（28例,1．37％）,感染型（391例,19．18％）和破裂型（298例,14．62％）,结论：首次提出与临床相结合的肝囊性包虫病影像学诊断的分型名称,分型的确定有助于选择手术方案,提高手术治愈率。

Imaging diagnosis and classification of hepatic cystic echinococcosis

Objective To investigate the imaging characteristics of hepatic cystic echinococcosis in different imaging examinations and to formulate an imaging classification Methods The data of pre operative imaging examination of 2 039 cases with hepatic cystic echinococcosis, who underwent operation during the period January 1984 to December 2000, by B mode ultrasonograohy (all cases), X ray computed tomography (909 cases), and magnetic resonance imaging (24 cases) were analyzed, being compared with the pathological findings of the resected specimens Results Imaging examinations suceeded to identify not only the location, size, and form of hydatid cyst in liver, but also the typical pathomorphology of complications The hepatic echinococcosis can be divided into seven imaging diadgnostic patterns: solitary cyst (1 625 cases, 79 70%), multiple cysts (414 cases, 20 30%), primary hydatid cyst with daughter cysts (1 114 cases, 54 63%), calcified cyst (186 cases, 9 12%), consolidated cyst (28 cases, 1 37%), cyst with infection (391 cases, 19 18%), and ruptured cyst (298 cases, 14 62%) Conclusion A new diagnostic system of hepatic echinococcosis has been formulated based on imaging examination and by reference to clinical manifestation It helps select appropriate operation program
