Abstract

We report a rare case of retroperitoneal pseudotumor caused by Schistosoma japonicum that was diagnosed by computed tomography (CT) guided percutaneous biopsy in a 15-year-old Filipino male. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a mass lesion, including a mesenteric artery, in the right retroperitoneal space. His mother had a history of S. japonicum infection but his initial stool examination was negative. As schistosomiasis was suspected, cone-beam CT-guided biopsy was performed to enable transcatheter therapeutic arterial embolization to be performed immediately in the event of hemorrhage. Histopathological examination revealed schistosomal eggs. Cone-beam CT-guided technique with a coaxial biopsy system is a safe and accurate diagnostic procedure for S. japonicum retroperitoneal pseudotumor.

锥形束ct引导同轴活检诊断日本血吸虫腹膜后假瘤1例。

我们报告一例罕见的由日本血吸虫引起的腹膜后假瘤，在15岁的菲律宾男性中通过计算机断层扫描(CT)引导下经皮活检诊断。计算机断层扫描(CT)和磁共振成像(MRI)显示肿块病变，包括肠系膜动脉，在右侧腹膜后间隙。其母亲有日本血吸虫感染史，但初步大便检查呈阴性。当怀疑为血吸虫病时，进行了锥束ct引导活检，以便在出血时立即进行经导管治疗性动脉栓塞。组织病理学检查发现血吸虫卵。锥形束ct引导技术与同轴活检系统是一种安全、准确的诊断日本血吸虫腹膜后假性肿瘤的方法。
