【摘要】 目的探讨阴茎阴囊转位的产前超声声像图特征。方法总结2例在胎儿系统超声检查中诊断为部分性阴茎阴囊转位胎儿的产前超声声像图表现,与引产后胎儿的生殖器形态特征进行对比,并对阴茎阴囊转位胎儿产前诊断的相关文献进行回顾分析。结果阴茎阴囊转位胎儿产前超声诊断的声像图典型表现为"郁金香"征,阴茎部分或完全位于阴囊下方,阴茎常表现为短小,合并尿道下裂时可根据胎儿排尿时CDFI检测确定尿道口的位置。结论产前超声检查是诊断胎儿阴茎阴囊转位有效可行的检测手段。在胎儿性别难以辨认时,应注意识别是否为阴茎阴囊转位畸形。更多还原

【Abstract】 Objective To assess the prenatal features of penoscrotal transposition by ultrasound. Methods The prenatal ultrasonogram of two fetuses, which were diagnosed as penoscrotal transposition, was retrospectively reviewed. The prenatal characteristics were summarized by ultrasound, and compared with those of autopsy. Literatures referring to the prenatal diagnosis of such abnormality were reviewed. Results The ‘tulip sign’ was characteristic prenatal ultrasound imaging of penoscrotal transposition with a bifid scrotum and hypospadias, which was partially or completely formed by the malpositioned scrotum anterior to the penis and the ventrally bent penis was located between the two scrotal folds. The color Doppler imaging of the micturating fetus may be helpful for display of dystopia of meatus. Conclusion Antenatal ultrasonography is an effective and feasible way to diagnose penoscrotal transposition. Penoscrotal transposition should be differentiated in case of ambiguous genitalia.更多还原
