Leptomeningeal contrast enhancement (LMCE) on magnetic resonance imaging (MRI) is a newly recognized possible biomarker\nin multiple sclerosis (MS), associated with MS progression and cortical atrophy. In this study, we aimed to assess the prevalence of\nLMCE foci and their impact on neurodegeneration and disability. Materials. 54 patients with MS were included in the study. LMCE\nwere detected with a 3 Tesla scanner on postcontrast fluid-attenuated inversion-recovery (FLAIR) sequence. Expanded Disability\nStatus Scale (EDSS) score, number of relapses during 5 years from MS onset, and number of contrast-enhancing lesions on T1\nweighted MRI were counted. Results. LMCE was detected in 41% (22/54) of patients. LMCE-positive patients had longer disease\nduration (
