Some may be associated with spinal dysraphism (e.g., a congenital dermal sinus), which may lead to bacterial meningitis caused by atypical organisms (e.g., Staphylococcus aureus, Escherichia coli, Proteus species, and anaerobes)
4/7
The presence of atypical pathogens, rather than typical pathogens such as Streptococcus pneumoniae or Haemophilus influenzae, suggests the presence of causative complications. 5/7
Initial antimicrobial therapy was adjusted to cefotaxime (CTX) based on susceptibility testing.
The response to treatment with CTX was partial (the CSF culture remained➕), and a switch to meropenem was required to achieve negative CSF cultures. 6/7
