[Epididymo-orchitis in a newborn: rare illness revealing late-onset Streptococcus agalactiae meningitis]. / Orchi-épididymite néonatale : une affection rare révélatrice d'un sepsis secondaire à streptocoque du groupe B.

Acute scrotum is unusual during the neonatal period. Testicular torsion is a surgical emergency aimed at salvaging the affected testis. Epididymo-orchitis is the main differential diagnosis, but few cases have been described in the newborn. Here, we report the case of a late-preterm infant who presented with late-onset group B streptococcal sepsis revealed by unilateral epididymo-orchitis.
