Fused variant of crossed testicular ectopia: A case report and discussion of the literature

Introduction

Crossed testicular ectopia (CTE) is a rare genitourinary anomaly in which both testes descend through the same inguinal canal.

Case presentation

We describe a 10-month-old boy with proximal penoscrotal hypospadias and nonpalpable right testis. Despite normal ultrasound findings on the left, the right testis was not visualized. Diagnostic laparoscopy revealed a right-to-left crossed fused ectopia through a left inguinal hernia. The fused testes were surgically dissected and bilateral orchiopexy was performed successfully.

Conclusion

Fusion variants of CTE are extremely rare. This case provides the first surgical description of infant fused CTE and highlights the importance of laparoscopy in management.
