Background

Multiple sclerosis (MS) is a chronic disease of the central nervous system. As an association between MS and reduced cerebral venous blood drainage was hypothesised, our aim was to compare the size of the jugular foramina in patients with MS and in control subjects.

Results

The mean diameter of the right foramen in patients with MS (6.3 ± 1.6 mm) was 10% smaller than that of the controls (7.0 ± 1.4 mm) (p = 0.020); the mean diameter of the left foramen in patients with MS (5.6 ± 1.3 mm) was 7% smaller than that of the controls (6.0 ± 1.3 mm) (p = 0.089). The sum of the diameters of both jugular foramina in patients with MS (mean 11.9 ± 2.3 mm) was 8% smaller (p = 0.009) than that of the controls (mean 13.0 ± 2.1 mm). The differences in diameters between patients with relapsing-remitting MS and patients with secondary progressive MS were not significant (p ≥ 0.332). There was no significant correlation between foramen diameters and the expanded disability status scale (p ≥ 0.079). Intra-reader and inter-reader reproducibility were 91% and 88%, respectively.

Conclusions

Jugular foramen diameter in patients with MS was 7-10% smaller than that in controls, regardless of the MS disease course.
