Unexpected sacrococcygeal teratoma diagnosed after birth in a term newborn

Abstract

Though rare, tumors in newborns are estimated with an incidence of 1 in every 12,500 to 27,500 live births, and they can become a complicated and significant problem for every neonatal unit, particularly in the absence of prenatal diagnosis. In this case report, we describe a patient with an unexpected sacrococcygeal teratoma, suspected on the first day after birth due to a gluteal asymmetry, investigated with ultrasound in a neonatal department and deepened with magnetic resonance, and finally referred to neonatal surgery consultants with final positive outcome.
