Abstract:
Here we report the first case of spontaneous occurrence of Haemophilus influenzae type B meningoventriculitis. A 47-year-old man suffered from fever and headache. He had neck stiffness, and his cerebrospinal fluid (CSF) was turbid and yellowish. Gram staining and latex agglutination test of his CSF indicated that Haemophilus influenzae type B was the causative organism. Cranial CT and MRI revealed right ventricular debris accumulation, periventricular hyperintense signal, and periventricular ependymal enhancement. He was treated with intravenous administration of antibiotics, and his clinical condition and MRI findings gradually improved. Six weeks after onset, he was discharged without sequelae.
Insights
This case study details the first spontaneous occurrence of Haemophilus influenzae type B meningoventriculitis. Prompt antibiotic treatment led to a full recovery without lasting neurological deficits.
Area of Science:
- Neurology
- Infectious Diseases
- Medical Case Reports
Background:
- Meningoventriculitis, inflammation of the meninges and brain ventricles, is a severe neurological condition.
- Haemophilus influenzae type B (Hib) is a significant cause of bacterial meningitis, particularly in unvaccinated populations.
Observation:
- A 47-year-old male presented with fever, headache, and neck stiffness.
- Cerebrospinal fluid (CSF) analysis revealed turbidity, Gram staining, and latex agglutination confirmed Haemophilus influenzae type B.
- Cranial CT and MRI showed ventricular debris, periventricular hyperintensity, and ependymal enhancement.
Findings:
- The patient was diagnosed with spontaneous Haemophilus influenzae type B meningoventriculitis.
- Intravenous antibiotic therapy was initiated for the confirmed Hib infection.
- Neuroimaging demonstrated a positive response to antibiotic treatment, with gradual resolution of abnormalities.
Implications:
- This case highlights the potential for spontaneous Haemophilus influenzae type B meningoventriculitis in adults.
- Early diagnosis and prompt antibiotic intervention are crucial for favorable outcomes.
- Successful treatment resulted in complete patient recovery without sequelae, underscoring the efficacy of timely medical care.
