Abdominal Neuroblastoma and Early Onset Acinetobacter Septicemia in a Newborn

Abstract

Background: Neonatal sepsis is a leading cause of mortality and morbidity in the first month of life. The underlying risk factors for early-onset infection (in the first 3 days of life) are prematurity, low birth weight, maternal history of infection, difficult delivery, male gender, twin pregnancy, and congenital malformations. Acinetobacter is a nosocomial infection and rarely caused the early-onset-sepsis and meningitis. The most common neonatal tumor is neuroblastoma; however, it is not defined as a risk factor for early-onset sepsis.  Case  report: A 13-day-old newborn female was referred to our hospital due to ventriculitis, persistent meningitis, and an abdominal mass. She was a term neonate delivered by cesarean section from a mother with a nearly normal pregnancy with no complications, such as chorioamnionitis, prolonged rupture of membrane, urinary tract infection, preeclampsia, and diabetes.  A fetal abdominal mass was detected on the left kidney in prenatal sonography. The patient was admitted to the Neonatal Intensive Care Unit in the first minutes of life because of respiratory distress and cyanosis. Subsequently, mechanical ventilation, endotracheal surfactant instillation, and antibiotic therapy were prescribed. Due to the deterioration of the general condition, fever, seizure, and hematuria on the third day, sepsis workup and changing the antibiotics were performed. Blood culture and cerebrospinal fluid (CSF) were positive for Acinetobacter baumannii. Persistent positive CSF culture led to the diagnosis of ventriculitis which was confirmed by brain computed tomography scan (CTS) and ventricular tap. The condition of the patient got better after intraventricular amikacin injection in addition to intravenous colistin and piperacillin.  Postnatal sonography and CTS confirmed the abdominal neuroblastoma. Chemotherapy was initiated after the complete treatment of sepsis, meningitis, and ventriculitis. This case report presents a term and female neonate with early-onset neonatal sepsis and  meningitis, caused by an unusual microorganism, and a prenatal history of abdominal neuroblastoma. Conclusion: By this case report, the clinicians are suggested to consider the Acinetobacter baumannii as the cause of fulminant sepsis and meningitis in a term neonate with no underlying risk factors for infection.
