Brain abscess caused by multidrug-resistant Acinetobacter baumannii. Case report.

This 24-year-old soldier had a history of polytrauma caused by firearm missiles of a fragmentation weapon. He was referred to the Hospital Militar Central, where multiple shrapnel wounds in the head, face, thorax, and extremities were found. A brain abscess was documented and drained, and a culture grew a multidrug-resistant Acinetobacter baumannii. An appropriate antibiotic treatment was started but did not lead to a good response, and the patient died. The clinical course of the illness is presented, as is its treatment and the role of A baumannii as an etiological agent of a brain abscess. To the authors' knowledge, there have been no reported cases in the worldwide literature of brain abscess by this infectious agent.
