"Clues on Balo's concentric sclerosis evolution from serial analysis of ADC values".

Balò's sclerosis is considered a rare variant of multiple sclerosis characterized by demyelination with concentric rings. Advanced magnetic resonance studies allow nowadays early diagnosis and prompt treatment. However, the pathophysiology of lesion evolution is still matter of debate, as detailed in our literature review. Based on a clear-cut Balò's lesion analysis, we describe early changes in DWI and ADC values within the different layers, favoring the concept of a centrifugal growth.
