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。
Objective: To study the relationship between CT manifestations and pathological changes of hepatic metacercariae. To further clarify the pathological significance of CT description and diagnostic value. MATERIAL AND METHODS: CT data of 16 patients with hepatic echinococcosis were analyzed with 16 pathological specimens of 15 patients. Results: (1) There was no blood supply structure in the focus of hepatic hydatid cyst. Although it contained a large number of dense small vesicles, CT mainly manifested as solid low density and no enhancement. (2) The calcification was the most common, the range and distribution of calcification (3) The liquefaction cavity is caused by the liquefaction and necrosis of the lesion, and the CT value of the cavity contents is close to water. (4) The pathological basis of the lesion is the larger vesicle or small liquefaction stove. Conclusion: There is a clear correspondence between CT and pathological changes of ECM. The value of CT diagnosis of the disease should be reflected in the combination form of its image manifestation.
