Prenatal ultrasound diagnosis of fetal testicular torsion: a case report / 中华围产医学杂志

ABSTRACT

This article reported a case of fetal testicular torsion diagnosed by prenatal ultrasound. Ultrasound examination at 38 weeks of gestation showed a slightly enhanced echo in the left testicle of the fetus and fluid accumulation within the testicular sheath cavity and between the sheath and fascia, presenting a 'double-ring' sign. An emergency cesarean section was performed considering the risk of acute fetal testicular torsion. Postnatal ultrasound images revealed abnormalities in the left testicle of the neonate and peripheral effusion with a 'double-ring' echo. The patient was considered to have congenital testicular torsion (with a high possibility of extravaginal type) and received an emergency treatment of left testicular torsion reduction combined with testicular fixation surgery and right testicular fixation surgery. Six months after surgery, reexamination by ultrasound showed the testicles of the newborn were normal.
