幼少女卵巢肿瘤的超声诊断分析

Ultrasonic diagnosis of ovarian tumors in immature females

目的探讨幼少女卵巢肿瘤的声像图特征及其超声诊断价值。方法选取年龄≤18岁且经手术病理证实为卵巢肿瘤的幼少女患者31例,回顾性分析其术前彩色多普勒超声检查资料,总结声像图表现,并结合临床和病理进行分析。结果 31例卵巢肿瘤患者中,经病理证实良性病变21例,交界性肿瘤1例,恶性肿瘤9例。其中以生殖细胞肿瘤最多见(61.3%)。11例超声表现为囊性者术后病理均证实为良性病变;5例超声表现为实性为主的占位,恶性占4/5;15例超声表现为混合性回声占位,恶性占4/15,其中3例内部均可探及血流信号,混杂或多房的混合性回声。结论幼少女卵巢肿瘤组织成分复杂,恶性率较高,超声声像图表现多样,但具有一定特征性,超声检查对幼少女卵巢肿瘤的诊断具有较高的准确率,可为临床诊断及治疗方案的选择提供帮助。

Objective To investigate the sonographic features and diagnostic value of ultrasonography in immature females with ovarian tumors.Methods Thirty-one immature females(aged ≤18 years old)with ovarian tumor confirmed by surgical pathology were selected. The preoperative color Doppler ultrasonographic data was retrospectively analyzed. The sonographic features,clinical manifestations and pathological results of them were analyzed.Results In 31 cases ,21 cases were benign tumors,1 case was borderline tumor,9 cases were malignant tumors.The pathology result showed that 61.3%(19/31)of the cases were germ cell tumor. 11 cases with cystic sonographic features were proved benign tumors by pathology. Solid tumor were most commonly associated with malignant(4/5).Amang the 15 cases of mixed echo occupying,maligant occupying 4/15,3 cases of them could detected the internal blood flow signal,mixed or multilocular mixed echo.Conclusion The malignant or benign pediatric ovarian tumors can be judged in most cases according to their sonographic characteristics,which offer important help in the clinical management.
