To assess prospectively the role of transvaginal ultrasonography in screening for cystic teratoma and in differentiating cystic teratoma from other ovarian masses.
Three hundred seventy-six premenopausal non-pregnant women underwent transvaginal ultrasonography 1 week before undergoing laparotomy or laparoscopy. The visualization of localized or diffuse echogenicity was chosen as the characteristic ultrasonographic finding of cystic teratoma. Endosonographic diagnosis was compared with surgical and pathologic findings.
Sensitivity and specificity for the ultrasonographic screening were 57.9 and 99.7%, respectively, calculated for each visualized ovary (n = 659), and 84.6 and 98.2%, respectively, for differentiating cystic teratoma from other ovarian masses, calculated for each visualized cyst (n = 123).
Transvaginal ultrasonography has a better predictive ability for differentiating cystic teratoma from other ovarian masses (kappa value 0.84) than in screening for cystic teratomas (kappa value 0.69).
前瞻性评估经阴道超声在囊性畸胎瘤筛查以及将囊性畸胎瘤与其他卵巢肿物相鉴别中的作用。
376名绝经前未孕女性在接受剖腹手术或腹腔镜检查前1周接受经阴道超声检查。将局限性或弥漫性回声增强的可视化表现选为囊性畸胎瘤的特征性超声表现。将超声诊断结果与手术及病理结果进行比较。
对每个可视化卵巢（n = 659）计算，超声筛查的敏感性和特异性分别为57.9%和99.7%；对每个可视化囊肿（n = 123）计算，在将囊性畸胎瘤与其他卵巢肿物相鉴别时，敏感性和特异性分别为84.6%和98.2%。
经阴道超声在将囊性畸胎瘤与其他卵巢肿物相鉴别方面（kappa值0.84）比在囊性畸胎瘤筛查方面（kappa值0.69）具有更好的预测能力。
