目的:分析儿童外周性原始神经外胚叶肿瘤/Ewing's肉瘤( Peripheral primitive neuroectodermal tumor/Ewing's sarcoma,pPNET/EWS)的超声声像图特点,提高该病的影像诊断准确率。方法:收集2012年4月-2018年5月我院确诊为pPNET/EWS的患儿共41例,总结分析其超声声像图特点。结果:男22例,女19例,平均年龄(7.68±4.35)岁。 pPNET/EWS好发于下肢和中轴部位骨和骨旁软组织深层,其中发生于骨19例,发生于软组织22例;均呈单发巨块状,超声测量肿瘤最大径平均值约10.10±4.48cm;包块形态不规则,边界可见;呈不均质中等回声(20例)或中等偏低回声(18例),少数为不均质低回声(3例);混杂细点状“针尖样”(28例)、簇状(24例)或条带状强回声(16例),亦可混杂散在小片状无回声区呈“蜂窝状”(19例),CDFI于其内可探及短条状血流信号,伴骨皮质破坏(19例)。结论:pPNET/EWS的超声声像图表现具有一定特点,超声可用于pPNET/EWS的诊断及随访。 |

Abstract: |
Objective To analyze the ultrasound image features of Peripheral primitive neuroectodermal tumor/Ewing's sarcoma (pPNET/EWS) in children, and to improve the accuracy of imaging diagnosis. Methods The sonographic features of 41 children who diagnosed as pPNET/EWS were analyzed in our hospital in April 2012 -2018 May. Results There were 22 males and 19 females with an average age of 7.68± 4.35 years. pPNET/EWS generally occurred in the Bone and soft tissue in of the lower extremities and the central axis. There were 19 cases occurred in Bone ,and 22 cases occurred in the soft tissue. The ultrasonic image also showed theirregular shape, visible border, single and giant mass, the average value of the maximum diameter of the tumor measured by Ultrasound was about 10.10cm, and the the mass appeared mostly medium (20/41,48.8%) or low echo (18/41,43.9%),A few cases are heterogeneous hypoechoic (3/41,7.3%).The mass might be mixed with high-echo dots("needlepoint-shaped")(28/41,68.3%), cluster (24/41,58.5%)or band-like strong echo(16/41,39.0%),also could be mixed with small region of scattered anechoic like"honeycomb"(19/41,46.3%) ,or showed cortical destruction (19/41,46.3%).CDFI detected short strip blood flow signals. Conclusion The sonographic features of pPNET/EWS have some characteristics, Ultrasound can be used for the diagnosis and follow-up of pPNET/EWS. |
