Correlations between conventional MRI measures of disease activity and clinical disability in multiple sclerosis (MS) have been disappointing. Because ring-enhancing lesions may reflect a more destructive pathology, we tested their potential association with disease severity. We evaluated active lesions with regard to their enhancement pattern on serial magnetic resonance images in a cohort of 28 patients with relapsing-remitting MS. The percentage of ring-enhancing lesions correlated with EDSS, T2 lesion load and duration of disease and predicted the occurrence of relapses during the baseline period of observation as well as after 3 years of follow-up in multiple logistic regression analysis. The findings suggest that the pathological process reflected by ring-enhancing lesions may contribute to more severe clinical disease.
