Abstract:
A 52-year-old man was admitted to our hospital because of two episodes of bacterial meningitis within a 6-month period. CSF examination showed neutrophilic pleocytosis with marked elevation of protein and hypoglycorrhachia, but the inflammatory reaction was mild and blood and CSF cultures were negative. At the time of the second admission, intermittent watery nasal discharge caused by CSF rhinorrhea was evident. CT and MR imaging revealed a tiny clival bone defect, and transnasal endoscopic repair was performed successfully. The pathological diagnosis was chordoma based on immunohistochemical staining for brachyury. Although chordoma presenting as recurrent bacterial meningitis occurs extremely rare, asking patients detailed questions about the CSF rhinorrhea must be essential for disclosing unclear infection sources.
Insights
Recurrent bacterial meningitis in a 52-year-old man was linked to a rare clival bone defect caused by chordoma. Prompt diagnosis involving CSF rhinorrhea assessment is crucial for identifying the infection source.
Area of Science:
- Neurosurgery
- Neurology
- Pathology
Background:
- Recurrent bacterial meningitis presents a diagnostic challenge, especially when initial cultures are negative.
- Cerebrospinal fluid (CSF) analysis can indicate inflammation but may not reveal the underlying cause.
- Identifying subtle anatomical defects is key to managing unexplained infections.
Observation:
- A 52-year-old male experienced two meningitis episodes within six months.
- Cerebrospinal fluid showed inflammation, but cultures were negative.
- The patient presented with intermittent cerebrospinal fluid (CSF) rhinorrhea during the second admission.
Findings:
- Imaging revealed a small clival bone defect.
- Pathological diagnosis confirmed chordoma via immunohistochemical staining for brachyury.
- Transnasal endoscopic repair of the defect was successful.
Implications:
- Chordoma can manifest unusually as recurrent meningitis, a rare presentation.
- Thorough patient history, including questioning about CSF rhinorrhea, is vital for diagnosing obscure meningitis.
- Early detection and surgical intervention for bone defects can prevent recurrent infections.
