This article from the journal "Neurology & Clinical Neuroscience" discusses a case study of a 29-year-old Japanese woman diagnosed with multiple sclerosis (MS) who developed a concentric lesion on her brain MRI. The three-dimensional imaging revealed a spherical concentric lesion that improved with treatment. The study suggests that the concentric lesion in MS may have developed from a central core, contributing to a better understanding of the pathogenesis of such lesions.
