Crossed testicular ectopia with preoperative ultrasound

Crossed testicular ectopia/transverse testicular ectopia is a rare congenital anomaly. It is most commonly identified intraoperatively in the setting of inguinal hernia repair with contralateral cryptorchidism. We report a case of crossed testicular ectopia identified in a 3-month-old male who presented with right cryptorchidism. Preoperative ultrasound revealed no testicle on the right and two testicles on the left - one within the left hemiscrotum and one within the left inguinal canal. Laparoscopy at 7 months of age revealed a closed right external ring and right ectopic testicle at the left external ring. Bilateral orchiopexy was performed.
