Polyorchidism: color Doppler ultrasonography and magnetic resonance imaging findings.

Polyorchidism, the presence of more than two testes, is a very rare anomaly. We report the color Doppler ultrasonography and magnetic resonance imaging findings of the case of a 20-year-old man with polyorchidism, presenting with an asymptomatic scrotal mass. Ultrasonography showed double testes with double separate epididymides sharing a common vas deferens in the left side of the scrotum. The double testes demonstrated similar echo texture and vascular flow as the normal testis, but smaller in size. Magnetic resonance imaging showed three testes very clearly and confirmed the diagnoses. After 2 years of follow-up, he was managed with surgical intervention. Pathology report revealed polyorchidism.
