肝吸虫病继发肝实质炎症的MRI增强表现

MRI enhancement presentation of hepatic parenchymal inflammation in clonorchiasis

目的总结肝吸虫病继发肝实质炎症的MRI增强表现。方法回顾性分析60例肝吸虫病继发肝实质炎症患者的临床及MRI资料。结果78.3%病灶分布右叶,21.7%病灶分布左叶;75%呈不规则形,25%呈假瘤样;强化类型100%表现为"快进慢出型",轻至中度强化;76.7%强化面积大于平扫,23.3%面积变化不明显。100%肝门区淋巴结均显影,85%肝门区淋巴结短径>1 cm。结论肝吸虫病继发肝实质炎症MRI增强影像表现具有一定特征性,有助于肝吸虫病的诊断。

Objective To summarize the MRI enhancement features of hepatic parenchymal inflammation(HPI)in clonorchiasis.Methods Clinical and MRI data of 60 clonorchiasis patients with HPI were retrospectively analyzed.Results Among 60 cases,78.3%HPI occurred in the right lobe and 21.7%in the left lobe;75%were irregular and 25%pseudotumorlike.All cases showed mild to moderate enhancement with fast wash-in and slow wash-out.The enhanced area was larger than nonenhanced one in 76.7%cases,while 23.3%showed no obvious change after enhancement.Hilar lymph nodes were evident in all cases,with the short diameter>1 cm in 85%.Conclusion The characteristic MRI enhancement of HPI is helpful to the diagnosis of clonorchiasis.
