摘　　要：目的探讨胎儿阴茎阴囊转位的声像图特征。方法应用二维联合三维超声对2015年1月至2017年2月中国医科大学附属盛京医院产前超声诊断(会诊2例)疑似阴茎阴囊转位的20例胎儿行多切面多角度扫查,随访胎儿染色体检查结果及妊娠结局,并结合相关文献总结胎儿阴茎阴囊转位产前超声声像图特征。结果 20例产前超声疑似阴茎阴囊转位的胎儿经产后检查证实17例为部分性阴茎阴囊转位,声像图表现为典型的"郁金香"征:阴茎部分位于阴囊下方,阴茎短小,位于分裂的阴囊之间,形似"郁金香";其余3例胎儿中2例为两性畸形,染色体核型为46-XX;1例基层医院会诊病例经产前超声诊断及生后随访证实为正常女性胎儿。结论胎儿阴茎阴囊转位有典型声像图特征,但需与两性畸形和阴茎发育短小等外生殖器异常影像进行鉴别,二维联合三维超声多切面多角度扫查有利于正确诊断。Objective To study the ultrasonographic features and differential diagnosis of fetal penoscrotal transposition.Two dimensional and three dimensional ultrasound were applied in the diagnosis of fetal penoscrotal transpositionto improve the detection rate.Methods Twenty cases of suspected penile scrotal transposition of the fetus in Shengjing Hospital affiliated to China Medical University fromJanuary 2015 to February 2017were included in present study.The ultrasound findings,fetal chromosome examination and clinical follow-up outcome were retrospectively summarized.Results Among the 20 suspected cases of penile scrotal transposition,17 cases were diagnosed correctly.All the 17 cases were partial type of penile scrotal transposition.In the remaining 3 cases,2 caseswere hermaphroditism with the karyotype of 46-XX,and the other 1 case was confirmed as normal female fetusesby clinical follow-up after birth.The″tulip″signwas the typical ultrasonographic features offetal penoscrotal transposition.Conclusion 2D combined with 3D ultraosound is useful in diagnosis and differential diagnosis of fetal penile scrotal transposition.
