Brain abscess in a neonate: an unusual presentation.

BACKGROUND

Neonatal brain abscesses are very rare and their clinical presentation is specific for this age group. They usually occur as a complication of bacterial meningitis or septicemia. They are most often caused by gram-negative organisms, and mortality and morbidity are still significant in this particular group of patients in spite of antibiotics and modern radiological tools.

METHODS

We report an unusual case of a multiloculated brain abscess in a term neonate caused by Staphylococcus aureus. The abscess developed in the absence of trauma, prior surgery, cyanotic heart disease, mother's disease, or immune defect. The onset of infection in this case was not clear and image features mimicked a brain tumor in the initial evaluation. The infant was successfully treated by primary surgical excision of the lesion and a 6-week total course of intravenous antibiotics.

CONCLUSION

The interest of this case lies in the rarity of the causative organism and the atypical features of clinical and neurological images in a term neonate.
