Diagnosis

Citrobacter meningoencephalitis

MR – Axial post-gadolinium T2 FLAIR and diffusion/ADC

Clinical – CSF and abscess specimens

Discussion

Citrobacter is a facultative anaerobic gram negative bacillus found in the intestinal tract and an exceedingly rare form of meningoencephalitis. Vertical transmission during the birth process is suspected but the source of infection cannot be identified in most cases. Citrobacter is the most common etiology for a brain abscess in a neonate; brain abscesses occur in 75% of patients with Citrobacter meningitis. Significant short-term and long-term neurological complications can be expected.
