目的:探讨MRI在肝脏炎性假瘤(IPL)诊断中的价值。材料与方法:回顾性分析经临床病理证实的16例肝脏炎性假瘤患者的MRI检查资料,并对其MRI表现和病理学检查结果进行对照。结果:16例共发现18个病灶。T1WI上13个病灶为低信号,5个为等信号;T2WI上14个病灶呈高或稍高信号,3个病灶为等信号。多期动态增强扫描显示IPL动脉期大多数病灶无明显强化,3个病灶可见强化;门静脉期和延迟期可见不同程度强化,强化方式多样,常见强化形式为周边不规则环形强化或结节状强化,或呈分隔样强化,且强化持续时间较长。结论:MRI多期动态增强扫描反映了IPL的病理学特征,对IPL的诊断与鉴别诊断具有重要价值。
Objective: To investigate the value of MRI in the diagnosis of inflammatory pseudotumor of the liver (IPL). Materials and Methods: MRI data of 16 cases of hepatic inflammatory pseudotumor confirmed by clinical pathology were retrospectively analyzed, and their MRI findings and pathological findings were compared. Results: A total of 18 lesions were found in 16 cases. Thirteen lesions on T1WI were low signal and 5 were equal signal. On the T2WI, 14 lesions showed high or slightly high signal and 3 lesions were equal signal. The multi-phase dynamic contrast-enhanced scan showed that most of the lesions in the IPL arterial phase had no significant enhancement and three lesions showed enhancement. The portal vein phase and the delayed phase showed various degrees of enhancement and various enhancement modes. Common enhancement forms were circumferentially irregular ring enhancement or nodular enhancement , Or were separated and strengthened, and strengthen the longer duration. Conclusions: MRI multi-phase dynamic contrast-enhanced scan reflects the pathological features of IPL and is of great value in the diagnosis and differential diagnosis of IPL.
