Listeria Meningitis in an Immunocompetent Child: Case Report and Literature Review

We present a case of a 23 month-old boy presenting with fever, irritability and diarrhea who subsequently developed symptoms of photophobia and lethargy. Cerebrospinal fluid culture grew Listeria monocytogenes. Immunology investigations were normal. This patient had a complete and uncomplicated recovery. Listeria meningitis is a rare presentation in immunocompetent children, but should be considered in the setting of diarrhea, failure to respond to cephalosporin therapy, or suspected immunodeficiency.
