| Abstract: | The authors report four observations of actinomycotic brain abcess. One patient with multiple hemispheric abcesses and with stomatologic and pulmonary lesions, one with seemingly primary cerebellar abcess, one with associated hemispheric abcess associated with pneumopathy. About these four cases, they discuss the role of actinomycosis in infectious diseases of the central nervous system, and the elements necessary for the diagnosis. The neurological syndrom is not specific, but the discovery of visceral lesions is an excellent argument. From the histological point of view, the discovery of "granules" containing the bacteria conforms the diagnosis by special colorations. From the bacteriological point of view, the isolation of the germ is easy but its specific identification necessitates special techniques. The diagnosis of actinomycosis is indispensible to begin a correct treatment. For the authors, this treatment must associate surgical excision of the most extensive lesions and adapted antibiotherapy for more than four months. |
