摘要
目的:探讨腹部炎性肌纤维母细胞瘤(IMT)的病理及影像学特征,以提高该病的诊断水平。方法:回顾性分析9例经手术病理证实的腹部IMT的影像学及临床资料。结果:9例IMT中,4例呈类圆形,2例呈椭圆形,1例呈葫芦形,2例呈不规则形;位于肝脏4例,胃2例,腹膜后2例,肠系膜1例;肿瘤直径为1.8~15cm;8例呈实性肿块,1例呈囊实性。CT/MRI平扫上,9例实性部分均呈低密度或T_1WI低信号、T_2WI混杂高信号;增强扫描上,9例动脉期均轻中度强化;静脉期及延迟期持续性强化。结论:腹部IMT临床少见,CT和MRI对该病的诊断具有一定的提示作用,但确诊仍需要依赖病理学检查。
Objective：To improve diagnostic level by investigating the image features correlating with pathological changes of abdominal inflammatory myofibroblastic tumor（IMT）.Methods：9patients with pathologically proved IMT were enrolled.Results：Among 9cases,the tumors showed round in 4cases,oval 2cases,gourd shape 1case,and irregular 1case.4cases located in the liver,2cases in the stomach,2cases adjacent to retroperitoneum and 1case adjacent to mesenterium.The tumors measured 1.8to 15.0cm in diameter.CT or MRI presented solid mass in 8cases,cystic and solid mass in 1case.The solid parts of all cases showed hypodense on non-enhanced CT,hypointense on T_1 WI and mixed hyperintense on T_2 WI.The enhancement patterns of the 9cases were various,showing striped,nodular and asymmetrical.All 9cases showed mild to moderate enhancement in arterial phase and persistent enhancement in venous and delayed phases.The margins of 7tumors were unclear and 2cases showed relatively clear.Conclusion：Abdominal inflammatory myofibroblastic tumor is rare.CT and MRI can show valuable characteristics of the tumor and provide some help for the diagnosis,but the confirmed diagnosis still depends on the pathological examination.
