Answer

Ventriculitis may occur through the involvement of the ependymal lining of the ventricles. This complication occurs in 30% of patients overall but is especially common in neonates, with an incidence as high as 92%. The organisms enter the ventricles via the choroid plexuses. As a result of reduced CSF flow, and possibly of reduced secretion of CSF by the choroid plexus, the infective organisms remain in the ventricles and multiply.
