Multiple brain abscesses in a newborn with Down syndrome: heart disease or meningeal infection?

Introduction: Cerebral abscess is a rare pathology in the newborn, most often secondary to meningeal involvement, but congenital heart disease is to be feared. Objectives: To review a case of multiple cerebral abscesses in the newborn with a doubtful diagnosis through a clinical case. Observation: Newborn at D6 of life, from a fullterm pregnancy, with a negative infectious anamnesis, admitted for fever at 38. The first one appeared at D4 of life, in whom the clinical examination found an icteric newborn, with a trisomic face, tachycardia at 180bpm, axial hypotonia, FANT and RS+, systolic cardiac murmur and light sub-costal draught. In front of this picture, a lumbar puncture was carried out objectifying a lymphocytic meningitis, At J8 of life, the newborn presented a convulsion, An ETF was carried out objectifying a hypoechogenic image with hyperchogenic border in cocarde evoking an abces confirmed by CT. The echocardium performed as part of the etiological workup, objective a single ventricle, CIA ostium primum large, IVC admission, single atrio ventricular valve, complete atrio ventricular canal, persistence of the ductus arteriosus and Coarctation of the aorta. The newborn was put on parenteral antibiotic therapy based on C3G meningeal dose + vancomycin + metronidazole by intravenous route then oral relay, with a scannographic control and neurological clinical evaluation. In front of this case, the question that arises: are his abscesses secondary to meningitis or to congenital heart disease? Conclusion: Brain abscess is a rare pathology, with heavy after-effects, and the prognosis of patients has improved thanks to the progress of imaging techniques, the use of ATB treatments, and minimally invasive neurosurgery. It is to be feared in front of congenital cardiopathies with right-left shunt.
