Until the nineteenth century this condition was fatal, however the development of neuroimaging for early diagnosis, neurosurgery and antibiotic therapy in the twentieth century has led to new therapeutic strategies decreasing mortality from 50\u200a% in the 1970s to less than 10\u200a% nowadays. In this context we report a case of brain abscess with a dental origin.\n <\/jats:p>\n \n Case report.<\/jats:bold>\n A immunocompetent man without any addiction presented to the emergency department with dysarthria and frontal headache at home. The clinical examination was normal. Further investigations revealed a polymicrobial brain abscess as a consequence of an ear, nose or throat (ENT) infection with locoregional extension with a dental starting point involving\n \n \n Actinomyces israelii<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n and\n \n \n Fusobacterium nucleatum<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n . In spite of a rapid diagnosis and a neurosurgical management associated with an optimal treatment by a dual therapy made of ceftriaxone and metronidazole the patient unfortunately died.\n <\/jats:p>\n \n Conclusion.<\/jats:bold>\n This case report shows that despite a low incidence and a good prognosis following the diagnosis, brain abscesses can lead to patient\u2019s death. Thereby, when the patient\u2019s condition and urgency allow, a thorough dental examination of patients with neurological signs following the recommendations would improve the diagnosis made by the clinician. The use of microbiological documentation, the respect of pre-analytical conditions, the interaction between the laboratory and the clinicians are indispensable for an optimal management of these pathologies.\n
