Hydatid disease (HD) is a unique parasitic disease that primarily affects the liver and is endemic in many parts of the world. There are four types of hydatid cysts (HCs) with various levels of organ involvement. All four HC types can be seen in the liver, with the right lobe being the most common site of involvement. There are many potential intrahepatic and extrahepatic complications that affect the liver and other organs. Intrahepatic complications include vascular and biliary complications and infection. With rare portal vein compression and decreased vascular supply, the involved lobe may show atrophic changes while the other lobe becomes hypertrophic. Intrahepatic biliary dilatation results from large cysts compressing intrahepatic ducts or due to cyst rupture into the biliary ducts. Cyst infection may also occur via a similar mechanism. Extrahepatic complications result from exophytic growth and hematogeneous dissemination. Exophytic growth causes migration of cysts into the lungs, mediastinum, heart and peritoneum. Hematogeneous dissemination involves all other organs.
包虫病（HD）是一种独特的寄生虫病，主要影响肝脏，在世界许多地区呈地方性流行。有四种类型的包虫囊肿（HCs），其累及器官的程度各不相同。所有四种HC类型均可在肝脏中见到，右叶是最常见的受累部位。存在许多影响肝脏和其他器官的潜在肝内和肝外并发症。肝内并发症包括血管和胆道并发症以及感染。在罕见的门静脉受压和血管供应减少的情况下，受累叶可能出现萎缩性改变，而另一叶则会肥大。肝内胆管扩张是由大囊肿压迫肝内胆管或囊肿破裂进入胆管所致。囊肿感染也可能通过类似机制发生。肝外并发症是由外生性生长和血行播散引起的。外生性生长导致囊肿迁移至肺、纵隔、心脏和腹膜。血行播散累及所有其他器官。
