Summary

Nearly half of British patients undergoing MRI for neurological issues had paranasal sinus abnormalities. Mucosal thickening in ethmoid sinuses was the most frequent finding in this magnetic resonance imaging study.

Area of Science:

  • Radiology
  • Otolaryngology
  • Neurology

Background:

  • Paranasal sinus abnormalities are common but their prevalence in specific populations undergoing neuroimaging is not well-defined.
  • Magnetic resonance imaging (MRI) is a key diagnostic tool for neurological conditions, often providing incidental views of the paranasal sinuses.

Purpose of the Study:

  • To determine the prevalence of abnormalities in the paranasal sinuses.
  • To identify common types and locations of these abnormalities in a British population undergoing MRI for neurological symptoms.

Main Methods:

  • Retrospective analysis of 130 patients' T2-weighted MRI scans.
  • Scans were assessed for common sinus abnormalities: mucosal thickening, fluid levels, sinus opacification, and retention cysts/polyps.
  • Focus on abnormalities appearing as high signal intensity on T2-weighted sequences.

Main Results:

  • 49.2% of patients exhibited at least one paranasal sinus abnormality.
  • Mucosal thickening was the most frequently observed abnormality.
  • The ethmoid sinuses were the most commonly affected anatomical region.

Conclusions:

  • A significant prevalence of paranasal sinus abnormalities exists in patients investigated for neurological conditions.
  • Findings suggest incidental sinus pathology is common on MRI scans for neurological indications.
  • Further investigation into the clinical significance of these incidental findings may be warranted.
