Abstract:
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.
