摘　　要：目的:分析腹部尤因肉瘤(ES)的常规超声及超声造影表现。方法:回顾性分析2016年1月—2022年6月于北京大学深圳医院经病理证实为腹部ES的3例患者的临床病理资料及超声影像资料,并进行随访。结果:3例腹部ES均表现为腹部巨大实性占位,2例同时累及肝脏及胆囊,1例为腹膜后单发病灶;3例均呈不规则实性占位,病灶内以低回声为主,中央可见无回声区,未见钙化,彩色多普勒血流成像(CDFI)均探及点状及条状血流信号。超声造影(CEUS)显示3例腹部ES均呈现动脉早期快速高增强,内见散在斑片状无增强区,门脉期或动脉晚期开始消退,肝内病灶廓清相对缓慢,静脉期呈低增强。2例病灶发生于肝脏者均于半年内复发或转移,1例发生于腹膜后者术后1年未见复发及转移。结论:腹部ES常规超声可表现为巨大实性占位,单发或多发不均质低回声团,CEUS表现为动脉早期快速不均匀高增强,其内可见出血、坏死所致无增强区。Objective The conventional ultrasound and contrast-enhanced ultrasound findings of abdominal Ewing sarcoma(ES)were retrospectively analyzed.Methods From January 2016 to June 2022,the clinicopathological data and ultrasonographic imaging of 3 patients with abdominal ES confirmed by pathology in Peking University Shenzhen Hospital were retrospectively analyzed and followed up.Results All 3 cases of abdominal ES showed large solid mass in the abdomen.2 cases involved the liver and gallbladder,while 1 case had a single lesion in the retroperitoneum.All 3 abdominal ES showed irregular solid occupancy with hypoechoic predominance in the lesion,anechoic areas in the center,no calcification,and color Doppler flow imaging(CDFI)detected both dot and strip blood flow signals.On contrast-enhanced ultrasound(CEUS),all 3 abdominal ES showed rapid and high enhancement in the early stage of the arterial phase.The washout occurred in the portal phase or later stage of the arterial phase,and became low enhancement during the venous phase.Non-enhanced areas were scattered within the interior.There were 2 cases of abdominal ES with liver invasion relapsed or metastasized within half a year,one case occurred in the retroperitoneum was no recurrence or metastasis for one year after surgery.Conclusion Abdominal ES can manifest as a single or multiple,large,solid,heterogeneous,and hypoechoic mass on conventional ultrasound.On CEUS,rapid and high enhancement in the early stage of the arterial phase can be found and non-enhancement areas caused by bleeding and necrosis are scattered within the internal.
