[Pasteurella multocida meningoencephalitis in a 14-year-old child].

Pasteurella multocida is generally responsible for local infections through animal bites. It can be a cause of meningitis, which tends to affect people at the extreme ages of life or suffering from immunodeficiency. A 14-year-old teenager was hospitalized with typical signs of bacterial meningitis. P. multocida was evidenced in the cerebrospinal fluid. Progression was marked by a degradation on the 4th day of treatment, despite intravenous antibiotic therapy with third-generation cephalosporin, followed by a single seizure on the 7th day of treatment. The CT scan and magnetic resonance imaging showed pansinusitis but no intracerebral complications. Later progression was favorable, without neurological sequelae. The mode of contamination was inoculation via the upper airways with sinusitis. P. multocida meningitis is rare. The contamination does not always involve animal trauma.
