Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare.
We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn't have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images.
Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions.
片形吸虫病是由片形科吸虫肝片形吸虫引起的疾病。胆管炎是一种常见的临床表现。尽管片形吸虫病可能表现出各种放射学和临床表现，但没有胆管扩张的病例很少见。
我们介绍了一个胆道片形吸虫病的独特超声（US）和磁共振胰胆管成像（MRCP）表现，该病例没有胆管阻塞或胆汁淤积。放射学上，在胆囊和胆总管内发现了与幼年和成年肝片形吸虫相吻合的弯曲寄生虫。这些寄生虫在 US 上表现为明亮的高回声结构，没有声影，在 T2 加权 MRCP 图像上呈低信号的弯曲病变。
影像学研究对具有细微临床和实验室表现的患者的诊断有重要意义，特别是在流行地区。
