Unlabelled:
Cases of meningitis due to Bacteroides fragilis are rare; we report a case revealing a meningorectal fistula.
Case Report:
A 2-month-old infant developed a severe sepsis syndrome following a rectosigmoidoscopy for rectal bleeding. Lumbar puncture diagnosed bacterial meningitis. Cerebrospinal fluid (CSF) culture evidenced B fragilis with betalactamase. The initial antibiotherapy was changed for imipenem-metronidazole, which is at present the recommended antibiotherapy. Malformation including pre-spinal tumor and meningorectal fistula was evoked on magnetic resonance imaging (MRI) and confirmed by surgery. The outcome was favorable after surgery and antibiotherapy.
Conclusion:
B fragilis meningitis are usually associated with sepsis, whose origin is obvious. In our case, meningitis was isolated, revealing a meningorectal fistula.
