Recurrent Pneumococcal Meningitis Secondary to Nasoethmoidal Meningocele.

Abstract

Since the widespread introduction of the conjugate pneumococcal vaccine and subsequent decline of invasive pneumococcal disease in children, a significant proportion of children with pneumococcal meningitis are identified as having an underlying immunodeficiency or predisposing anatomic abnormality. We present 3 cases of recurrent pneumococcal meningitis where detailed neuro-imaging revealed subtle anterior base of skull defects not detected on initial investigations.
