Evolution of T2 hyperintensities in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD)

(A) Axial FLAIR MRI reveals a T2 hyperintensity in the right cerebellar peduncle (A1, arrow) that resolved completely (A2) in follow-up. (B) Axial FLAIR MRI reveals T2 hyperintensities in the bilateral cerebral peduncles (B1, arrows) that resolved completely (B2) in follow-up. (C) Sagittal T2-weighted thoracic spine MRI reveals a longitudinally extensive T2 hyperintense lesion in the lower thoracic cord (C1, arrows) extending to the conus that resolved completely (C2) in follow-up.
