摘要
目的分析肝脏炎性肌纤维母细胞瘤(HIMT)病理特点及CT、MRI影像征象。方法回顾性分析本院2016年5月至2019年10月收治的13例HIMT患者的临床资料,记录肿瘤发生的部位、大小、形态、CT密度、MRI信号及强化特点,并与病理结果对照分析。结果13例HIMT患者中,单发病灶10例,多发病灶3例。肿瘤位置:肝左叶4例,肝右叶9例,肿瘤直径1.28cm~5.67cm,平均直径3.61cm。病理表现:2例可见假包膜;7例组织切面呈黄色,6例呈灰白色,可见脓液流出;CT可见6例呈圆形,4例呈椭圆形,3例呈葫芦状,病变边缘可见小棘样突起;3例患者MRI平扫时T2WI上呈高信号;9例动脉期无明显强化,门静脉期可见4例呈结节状强化,3例呈分隔状强化,6例边缘强化。结论HIMT的影像学表现具有一定的特征性,MRI和CT检查能够有效体现HIMT的病理特点,结合患者临床特征,可有效诊断和鉴别诊断HIMT。
Objective To analyze the pathological features of hepatic inflammatory myofibroblastoma(HIMT)and the CT and MRI imaging signs.Methods The clinical data of 13 patients with HIMT admitted to our hospital from May 2016 to October 2019 were retrospectively analyzed.The location,size,shape,CT density,MRI signal and enhancement characteristics of tumor were recorded and compared with pathological results.Results In the 13 patients with HIMT,10 had single lesions and 3 had multiple lesions,and tumor location in 4 cases was in the left lobe of the liver,9 cases in the right lobe of the liver,tumor diameter was 1.28cm~5.67cm,the average diameter was 3.61cm.Pathological manifestations:2 cases showed pseudo-envelop,tissue section in 7 cases were yellow,and tissue section in 6 cases were grayish white,with outflow of sanious.CT showed 6 cases with round shape,4 cases with oval shape,3 cases with the shape like CT showed 6 cases of round shape,4 cases of oval shape,3 cases of gourd-like,small spinous protrusions on the edge of the lesion can be seen.3 patients had high signal on T_(2)WI in MRI scan,9 patients had no obvious enhancement in arterial phase,4 patients showed nodular enhancement in portal vein,3 patients had septal enhancement,and 6 patients had marginal enhancement.Conclusion The imaging findings of HIMT have some characteristics.MRI and CT examination can effectively reflect the pathological features of HIMT.The clinical features of the patient are combined and the HIMT can be effectively diagnosed and differentially diagnosed.
