Liver hydatidosis is a parasitic endemic disease affecting extensive areas in our planet, a significant stigma within medicine to manage because of its incidence, possible complications, and diagnostic involvements. The diagnosis of liver hydatidosis should be as fast as possible because of the relevant complications that may arise with disease progression, involving multiple organs and neighboring structures causing disruption, migration, contamination. The aim of this essay is to illustrate the role of imaging as ultrasonography (US), multi detector row computed tomography, and magnetic resonance imaging (MRI) in the evaluation of liver hydatidosis: the diagnosis, the assessment of extension, the identification of possible complications and the monitoring the response to therapy. US is the screening method of choice. Computed tomography (CT) is indicated in cases in which US is inadequate and has high sensitivity and specificity for calcified hydatid cysts. Magnetic resonance is the best imaging procedure to demonstrate a cystic component and to show a biliary tree involvement. Diagnostic tests such as CT and MRI are mandatory in liver hydatidosis because they allow thorough knowledge regarding lesion size, location, and relations to intrahepatic vascular and biliary structures, providing useful information for effective treatment and decrease in post-operative morbidity. Hydatid disease is classified into four types on the basis of their radiologic appearance.
肝包虫病是一种寄生虫地方性疾病，影响着我们星球的广泛地区，由于其发病率、可能的并发症和诊断涉及的问题，在医学管理中是一个重要的问题。肝包虫病的诊断应尽快进行，因为随着疾病的进展，可能会出现相关的并发症，涉及多个器官和邻近结构，导致破坏、迁移、污染。本文的目的是说明超声（US）、多排探测器计算机断层扫描（CT）和磁共振成像（MRI）在肝包虫病评估中的作用：诊断、评估范围、确定可能的并发症以及监测治疗反应。US 是首选的筛查方法。CT 适用于 US 不足的情况，对钙化性包虫囊肿具有高灵敏度和特异性。磁共振是显示囊性成分和显示胆管树受累的最佳成像方法。CT 和 MRI 等诊断试验在肝包虫病中是强制性的，因为它们可以全面了解病变的大小、位置以及与肝内血管和胆管结构的关系，为有效治疗和降低术后发病率提供有用信息。根据其放射学表现，包虫病可分为四型。
