| 目的 探讨卵巢卵黄囊瘤（YST）超声特点。方法 回顾性分析经病理证实的12例卵巢卵黄囊瘤（共13个病灶）患者的二维声像、彩色多普勒及频谱多普勒超声表现，并与临床、病理表现对照。 结果 超声显示12例患者中，11例YST单侧单发，1例双侧单发，共13个病灶，瘤体中位径线11.82 cm×11.19 cm；13个病灶均呈囊实性混合回声，实性区域血流Adler半定量法分级均Ⅱ级及以上，阻力指数0.37~0.55；6例合并腹腔积液。病理显示2例有网膜或直肠陷窝转移，1例合并患侧输卵管、卵巢动静脉浸润。结论 YST具有一定的超声特征，但确诊必须结合临床表现，部分病例仍需病理免疫组化确诊。 |

| 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 ultrasonography, 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 Adler's 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 immunohistochemistry. |
