Radiological evidence of sinus infection in patients with multiple sclerosis
1MRC Environmental Epidemiology Unit, Southampton General Hospital.
Abstract:
The prevalence of radiological criteria of chronic sinus infection was compared in 42 cases of clinically definite or laboratory supported definite multiple sclerosis and 84 controls. No increase in relative risk of multiple sclerosis associated with the presence of chronic sinus infection was observed (odds ratio 1.2, 95% CI 0.5 to 3.1). The maxillary sinus was infected more often than the other paranasal sinuses but there was no difference in the distribution of infection within the sinuses between cases and controls. These results do not confirm an earlier report of an association between chronic sinus infection and multiple sclerosis.
Insights
This study found no increased risk of multiple sclerosis (MS) associated with chronic sinus infections. Radiological evidence of sinus infection did not differ between MS patients and controls.
Area of Science:
- Neurology
- Radiology
- Infectious Disease
Background:
- Chronic sinus infections have been anecdotally linked to multiple sclerosis (MS).
- Previous studies suggested a potential association between sinus pathology and MS development or progression.
- Clarifying this relationship is crucial for understanding MS etiology.
Purpose of the Study:
- To investigate the association between radiological evidence of chronic sinus infection and multiple sclerosis.
- To compare the prevalence of sinus infections in MS patients versus healthy controls.
Main Methods:
- Radiological criteria for chronic sinus infection were assessed.
- Prevalence was compared between 42 multiple sclerosis cases and 84 controls.
- Odds ratios and confidence intervals were calculated to determine risk.
Main Results:
- No significant increase in the relative risk of multiple sclerosis was observed in individuals with chronic sinus infection (odds ratio 1.2, 95% CI 0.5 to 3.1).
- The maxillary sinus showed higher infection rates, but this distribution was similar between MS cases and controls.
- Findings did not support a prior report suggesting an association.
Conclusions:
- The study does not confirm an association between chronic sinus infection and multiple sclerosis based on radiological findings.
- Further research may be needed to explore potential environmental or immunological links.
- The role of sinus infections in MS pathogenesis remains inconclusive.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
