[Actinomycotic cerebral abscess. Apropos of a case].

A case of an actinomycotic brain abscess in an adult patient apparently free of systemic infection is presented. The rarity of this etiology of brain abscess is underlined. The patient was treated by complete surgical excision and prolonged antibiotic therapy with penicillin. The authors stress the importance of taking into account this infrequent cause of brain abscess, the necessity of radical surgical treatment followed by intensive, prolonged and adequate antibiotic therapy, as the only means of reducing the high mortality rate.
