Complete epididymal separation presenting as polyorchidism.

We describe an unusual case of a 21-month-old boy with complete separation of the testis and epididymis. Two homogeneous structures were observed in the scrotum of a newborn boy in addition to a third structure. Polyorchidism was suspected, but follow-up sonographic studies showed a decrease in the echogenicity of the left scrotal structure. Surgical exploration revealed the testis and epididymis to be completely separated, with no duplicated testis. Orchidopexy was then performed.
