Intrauterine Testicular Torsion: Two Prenatally Diagnosed Cases and Review of the Literature.

Abstract

The third-trimester ultrasound diagnosis in two fetuses with isolated testicular torsion is described. Pregnancy courses were uneventful and routine second-trimester scans had shown no structural anomalies. Antenatal ultrasound performed at 32 + 3 and 33 + 0 weeks' gestation showed signs consistent with the diagnosis of isolated left spermatic cord torsion in both cases (absent flow across the testicular artery, hyperechogenic small rounded mass in the hemiscrotum representing the twisted testes, and hydrocele). Although testicular torsion may occasionally occur in utero, these acute events have been scanty reported in the prenatal literature. As a consequence of the ischemic injury, the rate of salvage of the affected testis is extremely low.
