摘要
目的探讨肝脏炎性肌纤维母细胞瘤（IMT）的影像表现特征，以提高影像诊断水平。方法回顾性分析经手术病理证实的12例肝脏IMT的影像表现，其中12例均行CT扫描，2例行MR检查。结果12例单发病灶均位于肝右叶。6例肿块为实性，4例肿块为囊实混合性，2例表现为门静脉周围浸润性病灶。CT图像上呈实性或囊实性低密度影，MR T1WI为低信号，T2WI为略高信号；增强扫描肿块实性部分呈均匀或不均匀中重度强化，囊实混合性病灶周边及灶内实性间隔呈蜂窝样强化。结论CT及MR检查能为临床诊断及鉴别诊断肝脏IMT提供有价值的信息。
Objective To describe the CT and MR imaging features of hepatic inflammatory myofibroblastic tumor（IMT）. Methods The CT （n = 12） and MRI （n =2） findings of pathologically proved hepatic IMT in 12 patients were retrospectively analyzed. Results All the tumors of the 12 patients were solitary and located in right hepatic lobe. Six tumors were solid and 4 tumors were solid-cystic. The other 2 tumors were periportal soft-tissue infiltration. The tumors appeared as solid or solid-cystic hypodense mass on CT images. The lesions were dark in T1-weighted sequences and slightly bright on T2-weighted sequences. There was homogeneous or inhomogeneous moderate to significant enhancement in solid portion of the tumors. Honeycomb-like enhancement was demontrated both in the peripheral part and at the intratumoral septa of the solid-cystic mass. Conclusion CT and MRI can provide helpful information for the clinical diagnosis and differential diagnosis of hepatic IMT.
