[A 6-week-old infant with failure to thrive: insidious presentation of group B streptococcal ventriculitis]. / Stagnation pondérale chez un nourrisson de six semaines : présentation insidieuse d'une ventriculite à streptocoque du groupe B.

ABSTRACT

Failure to thrive is frequently seen in breastfed infants. The most common diagnosis is insufficiency of breast milk in an otherwise healthy child. However, several differential diagnoses need to be considered. Progressive feeding difficulties and failure to thrive can be the first manifestation of group B streptococcal ventriculitis. This rare disease does not present with acute symptoms of sepsis or meningitis but evolves insidiously with no fever. Diagnosis is therefore often delayed and made only when intracranial hypertension develops. Cerebrospinal fluid (CSF) culture confirming the group B streptococcal infection and cerebral imaging are the necessary investigations for diagnosis. To our knowledge, only 10 cases have been previously reported.
