摘要
目的：研究肝泡球蚴病ＣＴ表现与病理改变之间的关系。进一步明确ＣＴ描述的病理学意义及诊断价值。 材料与方法：结合１５个患者的１６个病理标本对照观察，分析肝泡球蚴病患者的ＣＴ资料。结果：（１）肝泡球蚴病灶内无血供结构，虽含大量密集小囊泡，但ＣＴ主要表现为实性低密度且无强化；（２）伴随钙化最为常见，钙化的范围、分布和异形并存具有特点；（３）液化腔为病灶液化坏死所致，腔内容物ＣＴ值接近水；（４）小囊变灶病理基础是较大的囊泡或小液化灶。结论：肝泡球蚴病ＣＴ与病理改变存在明确的对应关系，ＣＴ诊断该病的价值应体现在其影像表现的组合形式上。
Purpose: To study the relationship between CT imaging features of alveolar hydatid of liver and its pathology,further confirm the senses of pathology and the efficacy of diagnosis about the terms of images used to describe on CT.Materials and Methods: The CT data of 16 specimens of 15 cases of the alveolar hydatid of liver were analysed by combing with pathological observations.Results: (1)There were quantities of metacestodes and not the structures of blood supply in the lesions of alveolar hydatid of liver, still CT main imaging teatures were solid form of hypodense that were not enhanced after the injection of venous contrast medium;(2)The rate of calcification was highest in the cases, and calcific extent, distribution and sharing various shapes had certain feature,(3)liguid cavities that CT values were close to water were formed by necrosis in the lesions: (4)Histopathologically small cystic areas corresponed to larger metacestodal vesicles or smaller liguefied necrosis,Conclusion: It is obvious that there are the corresponding relationship between CT imaging features of alveolar hydatid of liver and its pathology, In addition the diagnotic efficacy on CF ought to be embodied by compositive forms of CT imaging features.
