骨外尤文氏肉瘤的超声特征分析

Analysis of ultrasonic features of extraskeletal Ewing’s sarcoma

目的分析骨外尤文氏肉瘤(EES)的超声图像特征。方法回顾性分析我院经手术病理确诊的8例EES的超声图像表现,并对其进行术后随访。结果 8例EES患者均为单发肿块,其中发生于腹膜后4例,四肢软组织3例,躯干软组织1例。二维超声示肿块形态规则2例,不规则6例;边界清晰6例,欠清晰2例;8例肿块内部均表现为不均质回声,其中低回声6例,混合回声2例;7例肿块内未见明显钙化,1例肿块内可见钙化。CDFI示7例肿块内探及点状或线状血流信号,1例肿块内未探及明显血流信号。4例发生于腹膜后者均于1年内复发及转移;另4例失访。结论 EES可发生于腹膜后及四肢、躯干软组织,超声多表现为单发、形态不规则、边界清晰的不均质低回声团块。

Objective ultrasonic features of 8 cases of EES confirmed by pathology were retrospectively analyzed and followed up.Results8 patients showed a single mass,4 cases were located at the retroperitoneum,3 cases were located at soft tissues of limbs,and1 case was located at soft tissues of the trunk.Two-dimensional ultrasound showed that 2 cases with regular shape,and 6 cases with irregular shape.The margin of the tumors was clear in 6 cases and indistinct in the other 2 cases.All 8 cases were heterogeneous,6 cases were hypoechoic,and 2 cases were mixed echogenicity.No calcification was found in 7 cases,while calcification was found in 1 case.CDFI showed that dotted and linear blood flow signals found in 7 cases,and no unmistakable blood flow signal found in the rest 1 case.Recurrence and metastasis occurred within one year of the 4 cases located at the retroperitoneum,the other 4 cases were not followed up.Conclusion trunk,the ultrasonic features are primarily single,irregular shape,well-defined heterogeneous hypoechoic masses.
