Longitudinally extensive transverse myelitis with and without aquaporin 4 antibodies.
IMPORTANCE Aquaporin 4 antibody (AQP4-Ab)-negative patients with longitudinally extensive transverse myelitis (LETM) behave differently from those with AQP4-Ab. Aquaporin 4 antibody-negative neuromyelitis optica (NMO) is rare when good assays are used. OBJECTIVE To assess if AQP4-Ab-negative patients with LETM share similar disease characteristics with AQP4-Ab-positive patients or whether the...
متن کاملIdiopathic transverse myelitis: MR characteristics.
PURPOSE To describe the MR characteristics that can distinguish idiopathic transverse myelitis from other intramedullary lesions. METHODS A total of 32 initial and follow-up MR studies in 17 patients with clinically proved transverse myelitis were reviewed retrospectively. The location, size, pattern, and segmental length of areas of hyperintensity were estimated on T2-weighted axial and sagi...
متن کاملAquaporin-4 antibodies in neuromyelitis optica and longitudinally extensive transverse myelitis.
BACKGROUND There is increasing recognition of antibody-mediated immunotherapy-responsive neurologic diseases and a need for appropriate immunoassays. OBJECTIVES To develop a clinically applicable quantitative assay to detect the presence of aquaporin-4 (AQP4) antibodies in patients with neuromyelitis optica and to characterize the anti-AQP4 antibodies. DESIGN We compared a simple new quanti...
متن کاملReversible paraspinal muscle hyperintensity in anti-MOG antibody–associated transverse myelitis
Myelin oligodendrocyte glycoprotein immunoglobulin G (anti-MOG-IgG) has been recently found to be associated with some forms of idiopathic inflammatory demyelinating CNS disorders. In a preliminary study from India, recurrent optic neuritis and isolated longitudinally extensive transverse myelitis were identified as the common phenotypes. The clinical and radiologic features of this newly disco...
متن کاملTransverse myelitis.
Transverse myelitis (TM) includes a pathobiologically heterogeneous syndrome characterized by acute or subacute spinal cord dysfunction resulting in paresis, a sensory level, and autonomic (bladder, bowel, and sexual) impairment below the level of the lesion. Etiologies for TM can be broadly classified as parainfectious, paraneoplastic, drug/toxin-induced, systemic autoimmune disorders, and acq...
