Summary
This retrospective study aimed to assess the diagnostic value of ultrasound in children with transverse testicular ectopia (TTE). The study included 14 TTE patients, with a median age of 1.08 years. Physical examination identified 10 TTE cases, primarily with testes located in the opposite scrotum or groin. Ultrasound, conducted preoperatively, successfully diagnosed all 14 TTE cases and accurately determined the testes’ locations,
even within the abdominal cavity near the opposite iliac vessel. Ultrasound revealed ectopic spermatic cords in 42.8% of cases and persistent Müllerian duct syndrome (PMDS) in 7%. Diagnostic laparoscopy confirmed all TTE cases, with 85.7% showing ectopic spermatic vessels and vas deferens and 42.8% being associated with PMDS. Ultrasound was valuable in diagnosing TTE, while assessing the exact presence of PMDS remained challenging, possibly due to developmental factors, examination techniques, and atypical imaging findings in infants.
