摘　　要：目的:比较肝脏炎性假瘤的CT和MRI影像表现。方法:回顾分析2012年3月~2019年9月15例肝脏炎性假瘤患者的CT和MRI影像资料,所有患者均经手术病理确诊。结果:CT和MRI对肝脏炎性假瘤检出率均较高。CT平扫时炎性假瘤呈低、等密度,增强扫描动脉期多数病灶无强化,门脉期和延迟期可见不同程度强化。MRI平扫T1WI呈低信号和等信号,边缘相对清晰,T2WI信号表现不一,动态增强扫描与CT强化方式相近。结论:CT和MRI对诊断肝脏炎性假瘤均具有临床应用价值,可作为无创检查首选,但是除了影像学表现,还更应该结合患者临床症状及手术病理进行确切诊断。Objective:To compare the CT and MRI findings of inflammatory pseudotumor of liver.Methods:CT and MRI findings of 15 patients with inflammatory pseudotumor of the liver from March 2012 to September 2019 were retrospectively analyzed.All patients were confirmed by surgery and pathology.Results:The detection rate of inflammatory pseudotumor of liver by CT and MRI was high.On plain CT scan,inflammatory pseudotumor showed low and equal density.Most lesions in arterial phase showed no enhancement,while portal phase and delayed phase showed different degrees of enhancement.MRI showed low signal intensity on T1WI,and the edges were relatively clear.The signal of T2WI was different.The dynamic contrast-enhanced scanning was similar to CT enhancement.Conclusion:Both CT and MRI have clinical value in the diagnosis of inflammatory pseudotumor of liver,which can be used as the first choice of non-invasive examination.In addition to the imaging findings,the diagnosis should be based on the patient’s clinical symptoms and surgical pathology.
