Título

Brain abscess and empyema secondary to Pediococcus pentosaceus infection.

Fundamentação/Introdução

Pediococci are members of the lactic acid-producing family of facultatively anaerobic bacteria. This group of organisms, which also includes Lactobacillus and Leuconostoc species, recently have been found to be the cause of opportunistic infections in humans included bacteremic infections and septic shock secondary to a urinary tract infection.

Objetivos

To alert to the risk inherent from infection most likely associated a root canal treatment.

Delineamento/Métodos

Resultados

Brain CT and T2 sequence in Brain MRI demonstrated frontal brain abscess and subdural empyema. In the brain biopsy, the culture was positive by Pediococcus pentosaceus.

Conclusões/Considerações finais

Through this case, we have shown that members of the lactic acid-producing family of facultatively anaerobic bacteria can cause a serious infection. Nevertheless, with adequated treatment by antibiotic therapy, the pacient had only mild paresis of the sixth nerve.
