Sinusitis, particularly sphenoid sinusitis, may be linked to ischemic stroke. This study observed four patients with acute ischemic stroke and extensive sinus disease, suggesting a potential connection.

Area of Science:

  • Neurology
  • Otolaryngology
  • Radiology

Background:

  • The connection between sinusitis and ischemic stroke remains largely unexplored.
  • The anatomical proximity of paranasal sinuses to the internal carotid artery suggests potential pathways for inflammation to affect intracranial vasculature.

Observation:

  • Four patients presenting with acute ischemic stroke and extensive paranasal sinus disease were analyzed.
  • All patients experienced large vessel stroke within the internal carotid artery territory.
  • Magnetic resonance imaging revealed widespread sinus disease, notably involving the sphenoid sinus, in all cases.

Findings:

  • A potential association between paranasal sinus inflammation, specifically sphenoid sinusitis, and the occurrence of ischemic stroke is suggested.

  • The observed cases indicate that severe sinus disease may be a contributing factor in patients with internal carotid artery territory strokes.

    • Implications:

    • Further research is warranted to elucidate the causal mechanisms linking sinusitis to ischemic stroke.
    • This finding may encourage clinicians to consider sinus inflammation in the differential diagnosis of stroke patients with relevant imaging findings.
    • Understanding this relationship could lead to novel preventative or therapeutic strategies for ischemic stroke.
