Abstract

Extravaginal testicular torsion is known to be the predominant mechanism of the torsion in fetuses and neonates. In this torsion, twisting of the spermatic cord occurs outside the sac of the tunica vaginalis in the scrotum. Herein, we describe the sonographic findings of an extravaginal testicular torsion in a newborn baby who presented with a hard scrotal mass. Gray-scale ultrasound (US) showed hypoechoic linear striations in the testis with a thick hyperechoic peritesticular rim. Surgical exploration revealed an extravaginally twisted testis.
