[Multiple actinomycosis brain abscesses]. / Abcès cérébraux multiples à Actinomyces.

ABSTRACT

BACKGROUND: Actinomycosis is a subacute or chronic bacterial infection, which can affect immunocompetent or immunodeficient subjects. It most often occurs in cervico-facial or thoracic-abdominal locations. Central nervous system infection is rare but of severe prognosis. CASE REPORT A 56 year-old woman with no history of immunodepression was admitted with unexplained fever, inappropriate behaviour, and spatial and temporal disorientation. The progressive worsening of the neurological signs let to coma and mechanical ventilation was required. Brain imaging showed multilocation cerebral abscesses. Stereotaxial biopsy permitted diagnosis of actinomycosis. Patient's outcome was favourable following appropriate dual antibiotherapy without surgical exeresis. DISCUSSION: When lacking bacteriologic identification, diagnosis of cerebral actinomycosis is performed by pathologic findings. Dual antibiotherapy allows full recover, even in the case of multilocation cerebral abscesses.
