| [摘 要] 目的 分析骨外尤文氏肉瘤的超声图像表现。方法 回顾性分析8例经手术病理确诊的骨外尤文氏肉瘤的超声声像图特征。结果 8例患者均为单发肿块，4例发生于腹膜后，3例发生于四肢软组织，1例发生于躯干软组织。灰阶超声上见2例肿块表现为形态规则，6例表现为形态不规则。6例肿块边界清晰，2例边界不清晰。8例肿块内部回声均为不均质，6例主要为低回声，2例为混合回声。7例肿块内未见明显钙化，仅1例肿块内见多数钙化。CDFI示7例肿块内探及点线状血流信号，1例肿块内未探及明显血流信号。发生于腹膜后者均1年内出现复发及转移。结论 骨外尤文氏肉瘤超声声像图表现具有一定特征，但术前定性诊断仍较困难。 |

| Abstract: |
| [Abstract] Objective To analyze the ultrasonic appearances of extraskeletal ewing's sarcoma. Methods Ultrasonic features of 8 cases of extraskeletal ewing's sarcoma confirmed by pathology were retrospectively analyzed. Results The age of 8 patients ranged from 5 to 53 years old， the average age was 22 years old，The ratio of men to women is 3 to 5. All the 8 patients showed a single mass，4 of the tumors located at retroperitoneum，3 located at soft tissues of limbs and the other one at soft tissues of trunk. On the grayscale ultrasound images，2 cases presented regular shape and 6 cases presented irregular shape. The margin of the tumors was circumscribed in 6 cases and indistincted in other 2 cases. All the 8 cases were heterogenous，6 cases were hypoechoic and 2 cases were mixed echogenicity. No obvious calcification was found in 7 cases and most calcification was found in 1 case. In CDFI，5 tumors presented linear blood flow signals，2 tumors presented dotted blood flow signals and the rest 1 had no obvious blood flow signal.Recurrence and metastasis occurred within 1 year of the one located at retroperitoneum. Conclusion Extraskeletal ewing's sarcoma have certain ultrasonic characteristics, but the preoperative diagnosis via imaging techniques is diffcult，which is mainly confirmed by postoperative pathology and immunohistochemical analysis. |
