OBJECTIVE: To investigate the feature brain damage and clinical manifestations in neuromyelitis optica (NMO) patients; To investigate the relationship between serum NMO-IgG antibody and NMO brain damage. METHODS: Clinical data of 37 NMO patients and their head and spinal cord MRI by 1.5T superconducting MR scanner, were analyzed; serum NMO-IgG antibody were measured by immunofluorescence. RESULTS: 17 cases were found to have abnormal signals on MRI, which were mainly in the white matter, pons, medulla, ventricle, aqueduct, and around the corpus callosum; According to pathological changes, brain damage can be divided into scattered irregularity (13 cases), fusion (3 cases), multiple sclerosis-like (1 case), with scattered irregularity more common, 5 cases had clinical manifestations of brain damage: somnolence, vomiting, diplopia, visual rotation, 11 cases patients with brainstem damage show positive serum NMO-IgG antibodies


Objective: To compare spinal cord diffusion tensor imaging (DTI) between multiple sclerosis (MS) and neuromyelitis optica (NMO) subjects with a remote clinical episode of transverse myelitis (TM).


We retrospectively analyzed and compared patterns of anti-aquaporin-4 (AQP4) immunoreactivity of autopsied brains of 2 patients with classical multiple sclerosis (MS) and 2 patients with neuromyelitis optica (NMO). Serological examination for NMO-IgG was not performed in all the cases. We confirmed that the expression of AQP4 is strongly inhibited in demyelinating lesions of NMO, accompanied by the loss of grial fibrillary acidic protein (GFAP) expression


OBJECTIVE: Neuromyelitis optica (NMO) is an inflammatory disease associated with optic neuritis and myelitis. Although some studies have reported multiple sclerosis (MS)-like lesions in 10-30% of NMO patients, brain MRI is usually normal. Several studies have observed metabolic abnormalities on MR spectroscopy in MS, even in normal-appearing white matter (NAWM).
