Abstract：
Echinococcal disease (hydatid disease (HD) is an endemic parasitosis caused by Echinococcus granulosus in the larval stage, and it is typically due to the production of unilocular cystic lesions, usually involving the liver for the majority of patients and the lungs in 25%, but also any other organs can be potentially involved in developing echinococcal disease. We report a case of extrahepatic, retroperitoneal echinococcal disease, caused by Echinococcus granulosus. The patient underwent a surgical removal of the abdominal mass, revealed by abdominal ultrasound and computerized tomography scanning, and in the founded clinical and radiological suspicion of echinococcal disease, multiple bioptical samples were sent for microbiological analysis and albendazole therapy was started; Echinococcus granulosus protoscolices were found on the bioptical sample, and the diagnosis was successfully confirmed. According to the current parasitology literature on echinococcal disease, extrahepatic localization, although rare, can be found, and it should be considered in the differential diagnosis of an abdominal mass when epidemiological risk factors and anamnestic data are present, regardless of the usual site of the disease.
摘要：
棘球蚴病（包虫病（HD）是由细粒棘球蚴在幼虫期引起的地方性寄生虫病，通常是由于单眼囊性病变的产生，通常涉及大多数患者的肝脏和25％的肺部，但任何其他器官也可能参与发展为包虫病。我们报告一例肝外,腹膜后包虫病,细粒棘球蚴引起的.病人接受了腹部肿块的手术切除,腹部超声和计算机断层扫描显示，在临床和放射学怀疑的基础上，将多个生物样品送去进行微生物学分析，并开始阿苯达唑治疗；在生物样品上发现细粒棘球蚴，并成功确诊。根据目前有关棘球蚴病的寄生虫学文献,肝外定位,虽然罕见，可以找到,当存在流行病学危险因素和记忆障碍数据时，在腹部肿块的鉴别诊断中应考虑它，无论疾病的常见部位如何。
