Abstract:
Campylobacter fetus subspecies fetus (C. fetus) is a relatively rare cause of meningitis, with only 3 cases of C. fetus subdural empyema reported to date. We experienced a case of bilateral subdural empyema complicating C. fetus meningitis. A 51-year-old man was found lying unconscious on a street and was brought to the hospital in an ambulance. He had no past history of any underlying disease but he had suffered head trauma approximately 1 month prior to this episode. On admission, he had high fever and developed a convulsion fit. Because the cerebrospinal fluid (CSF) findings showed mononuclear dominant pleocytosis and Gram staining revealed spiral-shaped gram negative bacilli, meningitis caused by C. fetus was suspected. Brain CT preformed on admission did not reveal any obvious abnormality. He was immediately treated with antibiotics effective against C. fetus. His disease was complicated by bilateral subdural empyema; therefore, bilateral burr hole drainage was performed. Durling the operation, a hematoma with an outer membrane and containing yellowish pus was revealed. Infection of a chronic subdural hematoma and consequent formation of subdural empyema was deduced. Eventually, C. fetus was isolated from the CSF arterial blood and subdural empyema. The patient was discharged with no complication after the completion of the treatment.
Insights
Campylobacter fetus meningitis complicated by subdural empyema is rare. This case highlights a successful treatment of bilateral subdural empyema secondary to Campylobacter fetus meningitis.
Area of Science:
- Neuroscience
- Infectious Diseases
- Microbiology
Background:
- Campylobacter fetus subspecies fetus (C. fetus) is an uncommon cause of meningitis.
- Subdural empyema is a rare complication of bacterial meningitis.
Observation:
- A 51-year-old male presented with meningitis and subsequent bilateral subdural empyema after head trauma.
- Cerebrospinal fluid analysis revealed mononuclear pleocytosis and spiral-shaped gram-negative bacilli.
- Initial brain CT scan showed no abnormalities.
Findings:
- C. fetus was identified as the causative agent in cerebrospinal fluid, blood, and subdural empyema.
- The patient developed bilateral subdural empyema, necessitating surgical drainage.
- Infection of a chronic subdural hematoma led to subdural empyema formation.
Implications:
- This case underscores the importance of considering C. fetus in meningitis, especially with subdural empyema.
- Prompt antibiotic treatment and surgical intervention are crucial for favorable outcomes.
- Highlights the potential for C. fetus to cause severe neurological complications like subdural empyema.
