目的 分析总结肝炎性肌纤维母细胞瘤(HIMT)的超声表现特点.方法 回顾性分析2007年2月-2017年7月在盛京医院经病理证实为HIMT(4例)患者的超声图像特点,分析病灶的位置、大小、边界、形态、内部回声特点及血流情况.结果 患者年龄2 ～ 69岁,其中男性、女性各2例.4例患者均为单发,肿物最大径3.4 ～21.2cm.2例边界清晰,2例边界模糊.2例为实性,内呈不均质低回声,2例为囊实混合性,肿物内彩色多普勒血流成像均可检出血流信号.结论 超声检查能够较为明确地提示HIMT大小、内部回声特点及血流情况,但HIMT的超声图像缺乏特异性,确诊仍需病理组织学检查.%Objective To investigate the ultrasound features of hepatic inflammatory myofibroblastic tumor (HIMT).Methods A retrospective analysis was performed for the ultrasound features of 4 patients who visit Shengjing Hospital from February 2007 to July 2017 with pathologically confirmed HIMT,including the location,size,boundary,morphology,internal echo,and blood flow of lesions.Results The patients were aged 2-69 years and there were 2 male and 2 female patients.All 4 patients had single tumor with a maximum diameter of 3.4 -21.2 cm.Two patients had clear boundaries and two had unclear boundaries.Two patients had solid tumor with inhomogeneous low echo and 2 had mixed cystic and solid type;color Doppler flow imaging found blood flow signal in tumor in all patients.Conclusion Ultrasound can clearly reveal the size,internal echo,and blood flow of HIMT,but the ultrasound images of HIMT lack specificity.Pathological examination is still needed for a confirmed diagnosis.
