Objective: To observe the clinical value of prenatal ultrasound in fetal ovarian cyst torsion. Methods: A total of 7 cases of fetal ovarian cyst torsion were diagnosed using ultrasound images and clinical data were retrospectively analyzed

follow-up of newborns after birth

analysis of the ultrasound characteristics of fetal ovarian cyst torsion and the significance of early diagnosis. Results: There were one case which was confirmed to be vaginal atresia after delivery were misdiagnosed. All six cases of cysts showed complex cysts before delivery

six cases were larger than 4cm in diameter

one case was less than 4cm in diameter

six cases of seven cases were confirmed to be pedicle torsion of ovarian cysts after delivery

ultrasound diagnosis of ovarian. The total accuracy rate of fetal ovarian cyst torsion by ultrasound was 85.7%. Conclusion: Prenatal ultrasound can identify the torsion of the fetal ovarian cyst

which has important clinical value. Complex cysts with a diameter of more than 4 cm are the key indicators for the diagnosis of fetal torsion by prenatal ultrasound.
