摘　　要：目的探讨小儿骶尾部内胚窦瘤的超声特征,以提高诊断率。方法回顾性分析2011年1月至2019年3月经手术病理确诊的15例骶尾部内胚窦瘤超声表现。结果15例骶尾部内胚窦瘤均包绕尾骨呈膨胀性生长,形态不规则,部分呈分叶状,内部为实性不均质低回声,其中6例在低回声基础上含散在囊腔,2例含散在钙化点,15例血流信号丰富,其中2例显示迂曲血管回声。3例伸入椎间孔浸润椎管并骨质破坏,4例分别伴肝转移、肺部转移、腹膜后及盆腔淋巴结转移。骶尾部内胚窦瘤好发于婴幼儿女孩,本组男孩4例(26.7%),女孩11例(73.3%),男女比例1:2.8;年龄1~7岁,平均年龄2岁,<3岁者11例,占73%。结论小儿骶尾部内胚窦瘤超声图像具有一定的特征,超声检查无放射性损伤、无创、简单方便,可作为本病的首选检查方法。对于婴幼儿骶尾部形态不规则、含散在小囊腔、富血供、实性低回声包块,包绕尾骨生长、同时伴转移时,首先考虑为骶尾部内胚窦瘤。Objective To investigate the ultrasound features of endoembryoma in the sacrococcygeal in order to improve the diagnostic rate.Methods A retrospective analysis was performed on the ultrasound findings of 15 cases of patellar tail endodermal sinus tumors confirmed by surgical pathology from January 2011 to March 2019.Results In 15 cases,the endocervical sinusoidal tumors of the sacrococcygeal were expanded around the tail bone,with irregular shape and partial lobular shape,and the internal part was heterogeneous hypoechoic.Three cases of intervertebral foramen infiltrated the spinal canal with bone destruction,four cases were accompanied by liver metastasis,lung metastasis,retroperitoneal and pelvic lymph node metastasis.In this group,4 cases(26.7%)of boys and 11 cases(73.3%)of girls and 1:2.8%of men and women were found to have intra-sacral sinuses.the average age is 2 years old,of which 11 are less than 3 years old,accounting for 73%.Conclusion The ultrasound image of endoembryoma in children′s sacrococcyx has certain characteristics,and ultrasonic examination without radiation injury,non-invasive,simple and convenient,can be used as the first choice for the examination of this disease.For infants with irregular sacrococcygeal shape,scattered in the small capsule cavity,rich blood supply,solid hypoechoic mass,wrapped around the tail bone growth,accompanied by metastasis,the first consideration is the sacrococcygeal sinus tumor.
