目的 总结和探讨肝吸虫肉芽肿的CT、MRI表现及临床特点.方法 收集2010年1月-2015年9月于广西医科大学第一附属医院住院且经病理确诊的5例肝吸虫肉芽肿患者的临床及影像学资料,进行回顾性分析.结果 肝吸虫肉芽肿CT平扫表现为稍低密度,MRI平扫T1WI稍低信号,T2WI稍高信号.三期对比增强扫描均呈延迟强化表现,伴周围肝内胆管轻度扩张,病灶内可见正常血管通过.结论 肝吸虫肉芽肿临床罕见,食生鱼史、三期对比增强扫描呈延迟强化及病灶内有正常血管通过等特点有助于该病的诊断.%Objective To investigate the CT and MRI manifestations and clinical features of liver fluke granuloma.Methods A retrospective analysis was performed for the clinical and imaging data of 5 patients with pathologically confirmed liver fluke granuloma who were hospitalized in The First Affiliated Hospital of Guangxi Medical University from January 2010 to September 2015.Results Liver fluke granuloma had slightly low density on CT plain scan,as well as a slightly low signal on T1 weighted images and a slightly higher signal on T2 weighted images of MRI plain scan.Three-phase contrast-enhanced CT scan showed delayed enhancement with mild dilatation of the intrahepatic bile duct,and normal vessels ran through the lesion.Conclusion Liver fluke granuloma is a rare disease in chnical practice.A history of eating raw fish,delayed enhancement on three-phase contrast-enhanced CT scan,and normal vessels running through the lesion all contribute to the diagnosis of liver fluke granulomas.
