摘　　要：目的探讨磁共振显像(MRI)在肝脏炎性假瘤临床诊断中的价值。方法回顾性分析经病理证实的11例肝脏炎性假瘤(IPL)的MRI表现,并结合病理结果进行对比分析。结果11例中术前磁共振检查正确诊断4例,误诊为原发性肝癌1例、肝脏转移瘤1例、不典型血管瘤4例、肝脓肿1例。MR平扫11例中T1WI呈中等信号、T2WI呈稍高信号者6例;T1WI呈稍低信号、T2WI呈高信号2例;T1WI、T2WI均呈等信号2例;T1WI低信号、T2WI高信号、病灶周边伴环样长T2信号者1例。多期动态增强扫描,所有病灶动脉期均无强化。静脉期及延迟期呈周边环形强化7例,内见线样分隔强化者3例;附壁小结节样强化1例。结论IPL的MRI表现多样,与其病理结构及病程相关,MRI对IPL的诊断具有重要价值。Objective To assess diagnostic value of magnetic resonance imaging（MRI） for inflammatory pseudotumor of liver（IPL）. Methods MRI features in 11 patients with IPL proved by pathology and the relationship between MRI and pathological findings were reviewed and analyzed. Results Of 11 eases,4 were correctly diagnosed as benign lesions before operation,and the others were misdiagnosed as primary hepatic carcinoma（ 1 case） ,metastatic tumor of the liver （ 1 case） ,atypical angioma（4 cases） and hepatic abscess （1 case） respectively. On T1WI of MRI, The lesions were hypointense, slight hypointense or isointense relative to the liver, and on T2 WI of MRI, they were isointense or hyperintense. None of 11 IPLs showed strong enhancement during aterial phase. The lesions can demonstrate peripheral ring shaped enhancement （7 cases ）, centrie linear septation shaped enhancement （3 cases）, and enhancement of mural small node type （ 1 case） during portal venous phase and delayed phase. Conclusions MRI of IPL can presente heterogeneity due to its relation with pathological structure and the course of disease, and grasping the features of MRI could have important value for clinical diagnosis of IPL.
