目的 探讨超声对卵巢内胚窦瘤的诊断价值。方法 10例拟诊为卵巢内胚窦瘤的患者 ,术前 10 d行二维及彩色多普勒检查 ,观察其声像图特征 ,术后经病理组织学验证。结果 10例中有 8例为卵巢内胚窦瘤患者 ,超声诊断符合率为 80 %。其中 7例为单侧 ,1例双侧 ,声像图特征 :不均匀混合回声 ,见大片网状及囊状暗区。 1例为均质低回声。结论 以二维超声为基础 ,结合彩色多普勒血流显像 ,可以提高卵巢内胚窦瘤的诊断率。
Objective To investigate the diagnostic value of ultrasound in endodermal sinus aneurysm. Methods Ten patients who were diagnosed as endodermal sinus tumor of ovary were examined with two-dimensional and color Doppler before operation for 10 days. The sonographic features of the patients were confirmed by histopathology. Results 8 of 10 cases were patients with ovarian endodermal sinus tumor. The coincidence rate of ultrasound diagnosis was 80%. Seven of them were unilateral and one bilateral. Echographic features: Inhomogeneous mixed echoes, see large reticular and cystic dark areas. 1 case of low hypoechoic. Conclusion Based on two-dimensional ultrasound and color Doppler flow imaging, the diagnostic rate of ovarian endodermal sinus tumor can be increased.
