Transverse testicular ectopia with fused vas deferens

Abstract

Transverse testicular ectopia (TTE) is a rare congenital anomaly where both testicles are migrated in the same hemiscrotum or inguinal canal. The etiology is unknown and it has three types. Embryologically, several theories regarding the origin of TTE have been suggested including adhesion and fusion of developing Wolffian canals, aberrant gubernaculum, testicular adhesions, defective formation of the internal inguinal ring, and traction on the testis by persistent Mullerian structures. To date, more than 100 cases of TTE have been reported in the literatures. TTE with fused vas deferens is extremely rare. We present a case of 3 years old child referred for admission in our teaching hospital with right side inguinal hernia and left side undescended testis. After diagnosis with physical exam and ultrasonography, TTE was diagnosed and the child underwent inguinal herniotomy, ipsilateral orchiopexy and contralateral transseptal orchiopexy. The association of TTE with fused vas deferens is rare and transseptal orchiopexy is the procedure of choice for definite treatment.
