A rare case of Corynebacterium accolens isolated from brain abscess following mild nonpenetrating head trauma

Corynebacterium accolens ( C. accolens) was first described by Neubauer et al. in 1991. Infection of the CNS with this germ is still extremely rare and no previous case of brain abscess was reported yet. The authors report here the first case of brain abscess due to C. accolens, in a 60-year-old male patient after a nonpenetrating mild head trauma. Diagnosis was made after abscess aspiration followed by staining and incubation of the aspirate. Postoperative course was uneventful. This is the first reported case of brain abscess associated with C. accolens. The risk factors for this infection remain unclear. However, and for some unknown reasons, Corynebacterium may favor previously traumatized sites.
