Intraventricular (IVT) infusion of antimicrobial drugs could be a choice. This report aims to describe a patient with CNS infection caused by carbapenem-resistant Acinetobacter baumannii (CRAB) which was successfully treated with IVT combined with intravenous (IV) colistin sulfate.Methods: A case of CNS infection caused by CRAB after a craniocerebral injury was presented. The patient was treated with IVT together with IV colistin sulfate. Moreover, literature on the regimens and safety of colistin sulfate were also reviewed and summarized.Results: Intraventricular (50,000 U, qd/100,000 U, qd) combined with IV (500,000 U, q12h/500,000 U, q8h) colistin sulfate was given to the patient, and the CNS infection was successfully controlled. The patient was finally transferred back to a local hospital for rehabilitation treatment. No nephrotoxicity or neurotoxicity was observed during the therapy.Conclusion: IV combined with IVT colistin sulfate is effective in the treatment of CNS infections caused by CRAB. IVT concomitant IV colistin sulfate might be a therapeutic option worth considering in the treatment of CNS infections caused by CRO.Keywords: central nervous system infection, Acinetobacter baumannii, intraventricular administration, colistin sulfate, colistin, polymyxin
