Neuromielite óptica (NMO) é doença desmielinizante, remitente-recorrente, com acometimento predominante dos nervos ópticos e medula espinal e uma evolução mais grave comparada à esclerose múltipla. Estudos recentes demonstraram que até 50% dos pacientes com NMO podem apresentar lesões encefálicas à ressonância magnética (RM). Relatamos seis pacientes brasileiros com NMO, que satisfazem os critérios diagnósticos de Wingerchuck (1999) para NMO, com alterações encefálicas em RM de encéfalo e discutimos seus dados clínicos e de imagem.

Neuromyelitis optica (NMO) is a demyelinating disease consisting of relapsing-remitting optic neuritis and myelitis with a more severe course than Multiple Sclerosis. Recently, it has been shown that almost 50% of patients with NMO can have brain magnetic resonance imaging (MRI) abnormalities. We report on six Brazilian patients with NMO, fulfilling the 1999 Wingerchuck criteria for this disease, with abnormal brain MRI and discuss their clinical and radiological features.
