We studied cranial magnetic resonance imaging (MRI) lesions in three women with acute attacks ofrecurrent longitudinally extensive transverse myelitis (r–LETM), recurrent–optic neuritis (r–ON) andr–LETM–CNS. Neuromyelitis Optica –immunoglobulin (IgG) antibody was positive in all cases. BrainMRI (1.5 Tesla) was performed according to protocol from consortium MS centre. We described thecranial lesions in brain MRI of acute relapses. These lesions were different from MS, most had an asymptomaticcourse which disappeared with time, protocol from consortium of MS centre criteria for brainMRI and seropositivity of NMO–IgG are useful tools for differentiate acute lesions of NMO/MS. Key Words: neuromyelitis optica spectrum disorders; recurrent longitudinally extensive transversemyelitis; recurrent optic neuritis
