【摘要】：目的探討卵巢卵黃囊瘤(YST)超聲特點(diǎn)。方法回顧性分析經(jīng)病理證實(shí)的12例卵巢卵黃囊瘤(共13個(gè)病灶)患者的二維聲像、彩色多普勒及頻譜多普勒超聲表現(xiàn),并與臨床、病理表現(xiàn)對(duì)照。結(jié)果超聲顯示12例患者中,11例YST單側(cè)單發(fā),1例雙側(cè)單發(fā),共13個(gè)病灶,瘤體中位徑線11.82cm×11.19cm;13個(gè)病灶均呈囊實(shí)性混合回聲,實(shí)性區(qū)域血流Adler半定量法分級(jí)均Ⅱ級(jí)及以上,阻力指數(shù)0.37~0.55;6例合并腹腔積液。病理顯示2例有網(wǎng)膜或直腸陷窩轉(zhuǎn)移,1例合并患側(cè)輸卵管、卵巢動(dòng)靜脈浸潤(rùn)。結(jié)論 YST具有一定的超聲特征,但確診必須結(jié)合臨床表現(xiàn),部分病例仍需病理免疫組化確診。

Methods 12 cases of ovarian yolk sac tumor (13 lesions) confirmed by pathology were analyzed retrospectively. Results Ultrasound showed that 11 cases of YST were unilateral and unilateral, 1 case had 13 lesions, the median diameter of the tumor was 11.82cm 脳 11.19 cm, 13 lesions showed mixed echo of cystic and solid. The Adler semi-quantitative classification of solid regional blood flow was of grade 鈪，
