Polyorchidism with presumed contralateral intrauterine testicular torsion.

INTRODUCTION

Polyorchidism was first described by Blasius in 1670(1) during a routine autopsy. We report a child with unilateral polyorchidism and a contralateral absent testis, a combination not reported previously.

PRESENTATION OF CASE: A 2-year-old boy was referred to the outpatient clinic with an impalpable left testis. At laparoscopy, the left vas deferens and testicular vessels ended blindly proximal to a closed internal ring. No gonadal tissue was identified. On the right side, a single vas deferens and testicular vessels were seen entering the internal ring as normal. The right side of the scrotum was explored and two testes were identified within a single tunica vaginalis.

DISCUSSION: Polyorchidism is rare with a literature search identifying approximately 230 reported cases. Whilst prenatal testicular torsion is increasing being recognized and treated as a surgical emergency,(9) prenatal testicular torsion in association with polyorchidism has not been previously reported.

CONCLUSION

We describe a unique case of a 2-year-old boy with right-sided polyorchidism and an absent left testis associated with a blind ending vas deferens and testicular vessels, presumed secondary to intrauterine testicular torsion.
