Nosocomial Hemophilus influenzae type C meningitis in an adult
Diagnostic Microbiology and Infectious Disease
|January 1, 1987
Abstract:
Hemophilus influenzae type C meningitis developed in a 68-yr-old man with a cerebrospinal fluid leak which occurred after craniotomy for an olfactory groove meningioma. Hemophilus influenzae is an uncommon cause of meningitis in adults, and most reported cases have been due to type B or nontypeable strains.
Insights
A rare case of adult meningitis caused by Hemophilus influenzae type C occurred in a 68-year-old man following brain surgery. This highlights an unusual bacterial meningitis presentation in adults, distinct from common type B or nontypeable strains.
Area of Science:
- Neuroscience
- Infectious Diseases
- Neurosurgery
Background:
- Meningiomas are primary tumors of the meninges, often treated with surgical resection.
- Cerebrospinal fluid (CSF) leaks can occur post-neurosurgery, posing risks for infection.
- Adult meningitis is typically caused by Streptococcus pneumoniae or Neisseria meningitidis.
Observation:
- A 68-year-old male developed meningitis after craniotomy for an olfactory groove meningioma.
- The patient experienced a cerebrospinal fluid leak post-operatively.
- The meningitis was caused by Hemophilus influenzae type C.
Findings:
- Hemophilus influenzae type C is an infrequent cause of meningitis in the adult population.
- Most adult cases of Hemophilus influenzae meningitis involve type B or nontypeable strains.
- This case represents a rare instance of type C infection in an adult.
Implications:
- Cerebrospinal fluid leaks after cranial surgery necessitate vigilant monitoring for infectious complications.
- Clinicians should consider a broader range of pathogens, including less common strains of Hemophilus influenzae, in adult meningitis.
- Further research may be needed to understand the epidemiology of non-typable and specific serotypes of Hemophilus influenzae in adult meningitis.
