Crossed Testicular Ectopia in a Three-Year-Old: Case Report and Literature Review

Crossed testicular ectopia (CTE) is a rare congenital anomaly in which both testes descend toward the same hemiscrotum, with fewer than 150 cases reported in the literature. We present the case of a three-year-old boy who was admitted with swelling in the left inguinal region and bilaterally empty scrotum. Ultrasonography revealed one testis in the left inguinal canal and absence of the right testis. During inguinal exploration, both testes were found on the left side, confirming CTE. Each testis demonstrated normal morphology, vascularity, and adequate cord length, allowing successful left subdartos orchiopexy and right transseptal orchiopexy. The postoperative course was smooth, and follow-up confirmed proper placement of both testes in their respective scrotal compartments. This case emphasizes the importance of considering CTE in children with unilateral inguinal hernia and contralateral non-palpable testis and highlights the role of timely surgical intervention in preserving fertility and reducing malignancy risk.
