The hemoperitoneum is a rare and severe disease in neonatal period that can cause a condition of hemorrhagic shock. We presented the case of an infant hospitalized for hemodynamic disorders which could to suspect maternofetal infection. The clinical deterioration with the appearance of shock signs, anemia, abdominal distension and Ultrasound allowed to correct diagnosis. Labour dystocia (apart from unnoticed minimal obstetrical trauma) does not seem to be responsible for hemoperitoneum as the majority of the reported cases. According to current recommendations, the treatment of this condition is primarily based on reanimation measures. Surgery is rarely needed in certain cases. Conservative treatment should be considered.
