A rare case of cerebrospinal fluid (CSF) leak and meningitis was linked to unusual nasal polyps growing inside the brain. These polyps were attached to a bony outgrowth near the cribriform plate.

Area of Science:

  • Neurology
  • Otolaryngology
  • Pathology

Background:

  • Cerebrospinal fluid (CSF) rhinorrhea can result from various causes, including traumatic and non-traumatic intracranial pathologies.
  • Meningitis, an inflammation of the membranes surrounding the brain and spinal cord, can be a complication of CSF leaks.

Observation:

  • A 25-year-old male presented with spontaneous CSF rhinorrhea and meningitis.
  • Imaging revealed a complex intracerebral cystic lesion in the right frontal lobe.
  • A bony lesion was identified within the cyst, superior to the cribriform plate.

Findings:

  • Surgical exploration identified multiple pedunculated, grape-like cystic lesions with narrow stalks.
  • These lesions were attached to a bony outgrowth adhering to the right cribriform plate.

  • Histopathological examination showed the lesions were macroscopically and microscopically similar to nasal polyps.

    • Implications:

    • This case suggests an unusual etiology for intracranial lesions presenting as CSF rhinorrhea and meningitis.
    • The findings highlight a potential link between sinonasal pathology and intracerebral abnormalities.
    • Further research may elucidate the pathogenesis of such sinonasal-to-intracerebral polypoid growths.
