肝泡球蚴病的CT诊断

CT Diagnosis in Hepatic Alveolar Echinococcosis

笔者报告１８例肝泡球蚴病（泡型包虫病）的ＣＴ表现，主要特征为形态不规则、周界不清、密度不均（ＣＴ值：—１０～＋４０ＨＵ）病灶，内部或／和周边有多少不等的斑片状钙化（ＣＴ值：＋９０～＋３７０ＨＵ）；增强扫描病灶密度无变化。地图征型１２例，假囊型３例，周边晕影型３例。单发８例，多发１０例。笔者探讨了该病ＣＴ表现的病理基础及其与Ｂ超检查的相关性，并分析了该病与肝细粒棘球蚴病（囊型包虫病）和原发性肝癌的鉴别。

The CT findings of 18 cases of hepatic alveolar echinococcosis(alveolar hydatidosis) were analysed,including simple alveolar lesion in 8 cases and multiple lesions in 10 cases. The main CT features of the disease were irregular, heterogeneous lesions with ill-defined contour in the liver,having both hypodense(-10～+40HU)areas and calcifications (90～370HU).No significant enhancement was observed with in the lesions after administrtion of intravenous contrast medium. The correlation between CT and pathological findigs and US was reviewed.ifferential diagnosis with hepat-ic echinococcus granufosus(cystic hydatidosis)and primary hepatic carcinoma was also discussed.
