肝囊型包虫病超声影像进一步研究

A Further Study on Liver Hydatid Cyst with Ultrasonography

对１１５例肝囊型包虫病超声图像作了进一步分析，根据声像特征分为单纯囊型、多子囊型、继发征象型和多发病灶型四类。单纯囊型无育囊诊断较困难，是经皮穿刺引流治疗的适应症，继发征象型中囊肿实性变有时需结合流行病学进行诊断，囊壁呈双层，“囊砂征”，囊肿内显示子囊，内囊分离“套环征”，壁厚钙化，子囊钙化是囊型包虫病的典型特征。四型分类代表囊型包虫病发生、发展和转归的不同阶段，有助于本病的诊断与鉴别诊断并为手术及化疗适应症的选择提供参考资料。

in this report, we made a further analysis of ultrasonograms of 115 cases liver hydatid cyst. According to their ultrasonographic characters, we divided them into four types: simple cyst multiple cyst, secondary sign cyst, multiple focus cyst.It was difficult to diagnose simple tree as it had no brood cyst, which is the indication to the drainage treatment of skin puncture. Secondary sign cyst was solidified and had to be diagnosed with the help of epidemiology and the cyst wall shows double layers cyst-sand sign son cyst was shown inside cyst, inner cysts were separated,showing ″chain sign″, cyst wall was thick and was calcified. Calcified son cyst is the typical character of hydatid cyst. Dividing hy datid cyst into four types not only clearly shows teh occurrence, development and conversion, but also helps tO diagnose and identified liver hydatid cyst, and moreover offers the reference materials for the treatment by operation and chemotheraphy.
