Diffuse and heterogeneous T2-hyperintense lesions in the splenium are characteristic of neuromyelitis optica.
Brain Lesions May Serve as Diagnostic Criteria for Neuromyelitis Optica 2011;19(8):13. A majority of patients with neuromyelitis optica also experience disease-specific brain lesions that could help distinguish neuromyelitis optica from multiple sclerosis. MONTREAL—Imaging studies of patients with neuromyelitis optica (NMO)–spectrum disorders reveal that effects of the aquaporin-4 (AQP4) autoantibody, a marker of the disease, may extend beyond the spinal cord and optic nerve, according to researchers

BACKGROUND: Differentiating neuromyelitis optica (NMO) from multiple sclerosis (MS) is a real challenge in the clinical field. In the past, NMO (not MS), was inferred when abnormality was not detected in the brain magnetic resonance imaging (MRI). Recently, some studies have reported abnormalities in the brain MRIs of NMO, but only few among the Asian population.
Background: Neuromyelitis Optica (NMO) is a demyelinating disease of the central nervous system which preferentially involves the optic nerve and the spinal cord. This is the first inflammatory disease of the CNS in which a specific antibody (NMO-IgG) has been detected.
Background: Relapsing-neuromyelitis optica (R-NMO) is the first CNS inflammatory autoimmune disease with a defined target molecule: the astrocytic water channel aquaporin-4 (AQP4). We have reported structural brain abnormalities in R-NMO patients by visual analysis on MRI images
