Abstract:
Intracranial abscesses are serious conditions but uncommon in preterm neonates. Citrobacter species are an uncommon cause of bacterial meningitis in neonates, but are associated with brain abscesses in a majority of cases. We report a preterm infant who developed Citrobacter freundii meningitis with brain abscess, who was successfully treated with antibiotics and surgical drainage. The infant had normal neurological outcome at follow-up. We report this case to highlight the importance of serial neuroimaging in the diagnosis of cerebral abscess in infants with Citrobacter meningitis.
