| 目的 观察儿童尤因肉瘤(ES)常规超声及超声造影(CEUS)表现。方法 回顾性纳入经病理学确诊的15例ES患儿,分析其常规超声及CEUS特征。结果 15例ES中,骨尤因肉瘤(ESB)7例、骨外尤因肉瘤(EES)8例;14例单发肿物,最大径中位数7.50 cm,1例为腹腔多发肿物。超声显示肿物形态不规则、边界欠清,7例呈中等回声、6例呈低回声,2例为囊实性;CDFI显示11例存在少许血流信号、2例血流丰富、1例稍丰富,1例未见血流信号。7例接受CEUS,肿物均呈快速高增强、快速廓清,4例见散在无增强区。结论 ES常规超声表现具有一定特异性,CEUS呈"快进快出"并可伴坏死。 |

| Objective To observe conventional ultrasound and contrast-enhanced ultrasound (CEUS) manifestations of Ewing sarcoma (ES) in children. Methods Fifteen children with pathologically confirmed ES were retrospectively collected. Conventional ultrasound and CEUS characteristics of lesions were analyzed. Results Among 15 cases, ES of bone (ESB) was found in 7 cases, while extraskeletal ES (EES) was observed in the other 8 cases. Solitary tumor was noticed in 14 cases, with a median maximum diameter of 7.50 cm, while multiple abdominal masses were found in 1 case. The tumors had irregular shapes and poorly defined boundaries, with medium echogenicity in 7 cases, low echogenicity in 6 cases, while in other 2 cases present as cystic-solid lesions. CDFI showed sparse blood flow in 11 cases, abundant or slightly abundant blood flow in 2 and 1 case, respectively, while no obvious blood flow was observed in 1 case. Rapid high enhancement and rapid washout were found in all 7 cases underwent CEUS, while patchy no-enhancement areas were detected in 4 cases. Conclusion Conventional ultrasonic manifestations of ES had certain specificities, which demonstrated a rapid enhancement and rapid washout pattern during CEUS and may be accompanied by necrosis. |
