Abstract：
BACKGROUND: Hydatid cyst is a zoonotic disease caused by a tapeworm, Echinococcus granulosus. A retroperitoneal hydatid cyst is extremely rare and its diagnosis can be challenging, particularly in the early stage as it can mimic several regional pathologies like pancreatic pseudocyst, pancreatic neoplasm, and other retroperitoneal cystic lesions.
METHODS: We report a rare case of 39-year-old Nepalese male with a left retroperitoneal hydatid cyst who presented with pain and feeling of mass in the left flank region for 6 months. Diagnosis was made by abdominal computed tomography and magnetic resonance imaging and management was done by partial cystectomy.
CONCLUSIONS: Retroperitoneal hydatid cysts can present with chronic pain, mass, and symptoms resulting from the mass effect which varies according to the different retroperitoneal locations. Diagnosis of the retroperitoneal cyst can be challenging clinically and radiologically in its early stages. Even in the late stage, ultrasonography may not suffice and additional imaging techniques such as computed tomography or magnetic resonance imaging are required for the diagnosis.
CONCLUSIONS: In endemic areas, hydatid cyst should be considered while dealing with a retroperitoneal swelling for early diagnosis and prevention of rupture. With a high level of clinical suspicion and radiological findings, retroperitoneal hydatid cyst can be diagnosed and surgery is the principal method of treatment.

摘要：
背景：包虫囊肿是由a虫引起的人畜共患疾病，细粒棘球蚴。腹膜后包虫囊肿极为罕见，其诊断具有挑战性，特别是在早期阶段，因为它可以模拟胰腺假性囊肿等几种区域性病变，胰腺肿瘤,和其他腹膜后囊性病变。
方法：我们报告了一例罕见的39岁尼泊尔男性，患有左侧腹膜后包虫囊肿，表现为左侧区域疼痛和肿块感，持续6个月。通过腹部计算机断层扫描和磁共振成像进行诊断，并通过膀胱部分切除术进行治疗。
结论：腹膜后包虫囊肿可表现为慢性疼痛，质量,以及因腹膜后位置不同而产生的质量效应引起的症状。腹膜后囊肿的早期诊断在临床和放射学上可能具有挑战性。即使在后期，超声检查可能不够，诊断需要额外的成像技术，如计算机断层扫描或磁共振成像。
结论：在流行地区，在治疗腹膜后肿胀时，应考虑包虫囊肿，以便早期诊断和预防破裂。有了高度的临床怀疑和放射学发现，腹膜后包虫囊肿可以诊断，手术是主要的治疗方法。
