Abstract: Objective To explore the ultrasonographic features of yolk sac tumors of ovary.Methods Totally 12 patients (13 lesions) of the yolk sac tumors of ovary confirmed by pathology were analyzed retrospectively.Two-dimensional ultra sonography,color Doppler and spectral Doppler features were observed and combined with clinical manifestations.Results Ultrasound showed 1 case with bilateral single lesion and 11 cases with unilateral single lesion,the median size of tumors was 11.82 cm × 11.19 cm.Thirteen lesions showed liquid-solid mixed echo,and the blood flows in solid region were ≥ grade Ⅱ according to Adlefs semi quantitative method,the resistance index of blood was 0.37 0.55;Six cases combined with abdominal cavity effusion.Pathology showed 2 cases combined with omentum or rectal pouch metastasis and 1 case was tubal,ovarian artery and vein invasion.Conclusion Ultrasound images in the yolk sac tumors of ovary have characteristics and diagnosis must closely combine with clinical manifestations,some cases still need to be confirmed by pathology and immunohistochemist r y.
