Transverse testicular ectopia with Müllerian duct remnant in an incarcerated congenital inguinal hernia – a case report

BACKGROUND: Transverse testicular ectopia (TTE) is a rare anomaly characterized by both testes descending through a single inguinal canal. In this report, the diagnosis of TTE was discovered in the event of an incarcerated congenital inguinal hernia in a neonate. CASE PRESENTATION: We present a case of TTE accompanied by persistent Müllerian duct structures (PMDS) that had been discovered incidentally during inguinal exploration of a 26-day-old boy who presented with an incarcerated congenital inguinal hernia on the right side and left cryptochidism on the left side. The pathogenesis, approach and proposed management of TTE are discussed. CONCLUSION: TTE is an extremely rare anomaly, especially in neonates, and should be suspected in patients presenting with inguinal hernia on one side and cryptorchidism on the other side.
