Abstract：
Hydatid disease is a zoonosis caused by Echinococcus granulosus. Humans are aberrant intermediate hosts and following the infection, the parasite may infest any organ of the body, with the liver and lungs being the most involved organs. Portal vein involvement by hydatid cyst disease is extremely rare with only seven cases published to our knowledge. We present a 62-year-old Persian male with an incidental liver cyst. His laboratory tests were in normal ranges. The ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI) findings show hydatid disease of the liver with distal portal vein involvement and collateral venous formations. The patient is being followed and has not gone under surgery yet. It possesses a propensity to invade multiple organ systems, notably the liver and lungs. Hydatid disease is imposing a significant burden on healthcare systems specifically in developing countries. Manifestations of the disease are often non-specific, while a subset of the infected population remains asymptomatic. Portal vein invasion and obstruction is a rare complication, and it is important to distinguish it from vein thrombosis, as the management of these entities requires different approaches.
摘要：
包虫病是由细粒棘球蚴引起的人畜共患病。人类是异常的中间宿主，在感染后，寄生虫可能感染身体的任何器官，肝脏和肺是最受累的器官。包虫囊肿病累及门静脉极为罕见，据我们所知，仅有7例病例。我们介绍了一名62岁的波斯男性，患有偶然的肝囊肿。他的实验室检查在正常范围内。超声检查（美国），计算机断层扫描（CT）和磁共振成像（MRI）的发现显示肝脏包虫病伴远端门静脉受累和侧支静脉形成。患者正在接受随访，尚未接受手术。它有侵入多器官系统的倾向，尤其是肝脏和肺。包虫病给特别是发展中国家的医疗保健系统带来了沉重负担。这种疾病的表现通常是非特异性的，而一部分感染人群仍然无症状。门静脉侵犯和阻塞是一种罕见的并发症，区分它和静脉血栓形成是很重要的,因为这些实体的管理需要不同的方法。
