摘要
目的探讨卵巢内胚窦瘤原发及转移病灶超声声像图特征。方法回顾性分析35例卵巢内胚窦瘤患者19个原发病灶及33个转移病灶超声表现。结果本组卵巢内胚窦瘤患者19个原发病灶直径为(14.6±3.6)cm,所有病灶均为囊实性,实性部分以低回声及中等回声为主(16/19),血流较丰富。33个转移病灶多位于盆、腹腔(26/33),部分累及肝脏实质(7/33);26个盆、腹腔转移病灶直径分别为(9.4±4.5)、(9.2±4.9)cm,7个肝内转移病灶直径为(5.6±1.6)cm;盆、腹腔转移病灶多为低回声(21/26),肝内转移病灶主要为高回声(5/7)。9个(9/26)转移病灶为囊实性,血流较原发病灶少。血清甲胎蛋白(AFP)水平均有不同程度升高,为217～211 682μg/L。结论卵巢内胚窦瘤原发及转移病灶的超声表现有一定特征,结合血清AFP水平进行判断可提高诊断准确率。
Objective To investigate ultrasonographic features of primary and metastatic ovarian yolk sac tumors.Methods Ultrasonographic features of 19 primary lesions and 33 metastatic lesions in 35 patients were retrospectively analyzed.Results Primary tumors were sized （14.6±3.6）cm in maximum diameter,manifesting as cysti-solid masses.Solid components of primary tumors were mainly hypoechoic or isoechoic（16/19）with rich blood supplies.Thirty-three metastatic lesions were located in pelvoceliac cavity（26/33） and liver parenchyma（7/33）,sized （9.4±4.5）cm,（9.2±4.9）cm and （5.6±1.6）cm in maximum diameter respectively.Metastatic lesions in pelvoceliac lesions mainly demonstrated as hypoechoic masses（21/26）, however lesions in the liver were mainly hyperechoic（5/7）.Anechoic regions could be found in 9/26 of the pelvoceliac lesions.Blood supply was found less rich in metastatic masses than that in primary ones.Elevated serum level of alpha fetoprotein （AFP） was observed in all patients; ranging from 217 to 211 682 μg/L.Conclusions Primary and metastatic lesions of ovarian yolk sac tumor have obvious ultrasonographic characteristics.Combined with serum AFP level,the accuracy of diagnosis could be improved.
