title: Sonographic features of polyorchidism.
abstract: We describe a case of polyorchidism diagnosed sonographically. Palpation revealed a nontender oval mass, about 1 cm large, inferior to the left testis. Sonography identified the mass as an accessory testis that measured 1.0 x 0.8 x 0.6 cm and had its own epididymis. The echotexture in the accessory testis was similar to that in the normal testes, and color Doppler sonography demonstrated that it had normal blood supply. MRI confirmed these findings. High-resolution sonography is an effective, noninvasive means of accurately diagnosing polyorchidism without the need for exploratory surgery.
