Abstract

Perinatal testicular torsion, defined as torsion occurring in the prenatal period or in the first month after birth, accounts for 10% of all cases of testicular torsion in pediatric patients. Most are extravaginal, and intravaginal torsion is rare. Its management is controversial, due to the low viability of the testis and the possibility of bilateral torsion. Ultrasonography is the method of choice to study testicular torsion. Combining B-mode and power Doppler imaging facilitates a fast reliable diagnosis. We review the ultrasonographic appearance of neonatal testicular torsion for each presentation, the differential diagnosis with other causes of increased scrotal volume in neonates, and its treatment.

Resumen

La torsión testicular perinatal constituye el 10% de las torsiones testiculares en la edad pediátrica y se produce en el periodo prenatal o neonatal durante el primer mes de vida. La mayoría son extravaginales, siendo improbable la torsión intravaginal. Su manejo es controvertido debido a la baja viabilidad del testículo y a la posibilidad de torsión bilateral. La ecografía es el método de elección para su estudio. La combinación del modo B con el Doppler color o el power Doppler facilita el diagnóstico de forma rápida y segura. Revisamos la apariencia ecográfica de la torsión testicular neonatal en cada una de sus formas de presentación, el diagnóstico diferencial con otras causas de aumento de la bolsa escrotal en el neonato, y finalmente su tratamiento.
