Fulminant citrobacter meningitis with multiple periventricular abscesses in a three-month-old infant

citrobacter, a gram-negative enteric bacillus, is a rare cause of septicemia and meningitis, seldom reported beyond the neonatal period. it is characterized by a fulminant clinical course and a high incidence of complications, including brain abscesses. we studied a three-month-old infant with citrobacter meningitis, who developed acute communicating hydrocephalus and multiple periventricular brain abscesses while on treatment. the patient died, despite intensive antibiotic treatment directed towards the causative organism, c. diversus.
