Brain abscess secondary to a dental infection

The multiplicity of possible sources of infection and the diversity of oral bacteria mean that the implication of dental infection in brain abscesses is indicated by the failure to find any other infection source, the presence of oral microflora in the abscess microbiological spectrum, and clinical and radiographic signs of dental infection [5]. Frequently associated with brain abscess in adults and children, Streptococcus intermedius is a commensal bacterium found in the oral cavity and gastrointestinal tract [6, 7]. The discovery of this organism in bacteriological cultures should lead the clinician to consider an oral and dental aetiology. In this case report, the delay between neurosurgical and dental procedures is explained by the lack of knowledge of this dental aetiology. Fortunately, the patient made a full recovery without sequelae, but morbidity of brain abscesses can reach 53% and mortality 16% of cases
