Community-acquired Acinetobacter baumannii bloodstream infection with central nervous system involvement: a case report.

OBJECTIVE

This study reports a rare case of community-acquired Acinetobacter baumannii bloodstream infection complicated by central nervous system (CNS) involvement, providing insights into its clinical characteristics, diagnosis, and treatment.

METHODS

A 76-year-old woman presented with fever, chills, and altered mental status. Blood and cerebrospinal fluid cultures confirmed A. baumannii infection, with no evidence of pulmonary involvement.

RESULTS

The patient was successfully treated with a combination of meropenem and both intravenous and intrathecal colistin methanesulfonate.

CONCLUSION

While A. baumannii is primarily associated with hospital-acquired infections, this case highlights its potential to cause severe community-acquired bloodstream infections with CNS involvement.
