摘要
本文报道67例肝细粒棘球蚴病的CT表现,其中包括单房性包虫囊肿32例、多房性包虫囊肿35例。囊肿有钙化42例,并发破裂/感染34例。作者认为本病最主要的CT表现为肝内有边缘光滑、密度均匀的圆形或卵圆形阴影,CT值近于水。囊壁的显示及其钙化、子囊的存在,囊膜剥离征则具有特征性,可作为CT诊断本病的重要依据。作者探讨了本病CT表现的病理基础,并提出与肝囊肿、肝脓肿、坏死性或囊性肝转移瘤以及少见的肝内胆管癌和特殊的肝癌的鉴别。
CT findings in hepatic echinococcus granulosus were analyzed, including simple cystic lesion 32, and multivescular lesion 35 cases. Calcifications were demonstrated in 42 cases. In 34 cases there were signs of perforation and infection. The main feature of the disease revealed an oval or rounded smoth cystic wall with watery density. The predominant signs were presence of cystic wall, rimcalcification, daughter cyst and detached membrane. The correlation between CT and pathological findings of the disease was reviewed. Differential diagnosis with liver cyst, liver abscess, necrotic/cystic metastatic tumor, intrahopatic cholangio carcinoma and specific primary hepatic carcinoma was also discussed.
