Spinal cord and brain corticospinal tract lesions are associated with motor progression in tumefactive multiple sclerosis.

Background: Spinal cord lesions have been associated with progressive disease in individuals with typical relapsing remitting MS (RRMS).

Objective: In the current study, we aimed to determine if progressive disease is associated with spinal cord lesions in those with tumefactive multiple sclerosis (MS).

Methods: Retrospective chart review of individuals presenting to Mayo Clinic with tumefactive MS with spinal cord MRIs available (n=159).
