肝脏炎症性肌纤维母细胞瘤临床及多排螺旋CT表现

摘要

Aim:To investigate clinical and multiple spiral (MSCT) manifestation of hepatic inflammatory myofibroblastic tumor (IMT) aiming to increase awareness of this disease.Methods:Retrospective analysis was used to explain clinical and MSCT manifestation in 9 cases,which had been pathologically confirmed after operation.Results:Eight tumors located in right hepatic lobe and 1 case located in left hepatic lobe; round and orbicular-ovate shape for 7 cases and lobulation in 2 cases; MSCT plain scan showed low density,and patchy calcification presented in 2 focuses; there was no significant intensification after strengthening posterior artery,portal and delay phases (n =2),separated like reinforcement (n =3),and edge irregular reinforcement (n =4).MSCT multiplanar reconstruction benefited comprehensively displaying the relationship between hepatic IMT growth pattern as well as focuses and hepatic tissue,biliary tract,as well as blood vessel.Conclusion:Hepatic clinical manifestation of IMT had no significant characteristics,and MSCT image features benefited hepatic IMT diagnosis and identification.%目的:探讨肝脏炎症性肌纤维母细胞瘤(IMT)的临床和多排螺旋CT (MSCT)表现特征,旨在提高对该病的认识.方法:回顾性分析9例经手术病理证实肝脏IMT的临床表现和MSCT表现特征.结果:8例位于肝右叶,1例位于肝左叶；圆形和卵圆形7例,分叶形2例；MSCT平扫均表现为低密度,2例病灶内有斑片状钙化；增强后动脉、门脉期及延迟期均无明显强化2例,分隔状强化3例,边缘不规则强化4例；MSCT多平面重建有助于全面地显示肝脏IMT的生长方式、病灶与周围肝组织、胆道和血管的关系.结论:肝脏IMT临床表现无明显特征性,MSCT影像特征有助于肝脏IMT的诊断和鉴别诊断.
