Classical symptoms consisting of headache, fever, and focal signs may be absent on admission and brain MRI with contrast plays a major role in diagnosis. Initial management consists of stereotactic aspiration for microbiological documentation empirical treatment covering common pathogens, including oral streptococci, staphylococci, anaerobes, and Enterobacteriaceae. De-escalation of antimicrobials based on microbiology is safe only when samples have been processed optimally, or when primary diagnosis is endocarditis. A 6-week combination of third-generation cephalosporin and metronidazole will cure most cases of community-acquired brain abscess in immunocompetent adults. Significant advent in brain imaging, minimally invasive surgery, molecular biology, and antibacterial agents, has dramatically improved the prognosis. Main indicators of outcome include altered mental status at presentation and intraventricular rupture. Langue : ANGLAIS |
