Cervical spinal cord atrophy in NMOSD without a history of myelitis or MRI-visible lesions
نویسندگان
چکیده
Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease that usually presents with optic neuritis or severe myelitis. NMOSD can be diagnosed after only one typical clinical syndrome if immunoglobulin G (IgG) antibodies against the aquaporin-4 receptor (NMO-IgG) are present. Patients with NMOSD can develop marked spinal cord atrophy after myelitis, but it is unknown whether atrophy can occur without a history of myelitis. To address this question, we compared the mean upper cervical cross-sectional area (MUCCA) in patients with NMOSD without MRI cord lesions or history of myelitis, patients with NMOSD with MRI cord lesions or history of myelitis, patients with multiple sclerosis (MS), and neurologically intact controls.

Comparison of clinical characteristics between neuromyelitis optica spectrum disorders with and without spinal cord atrophy
BACKGROUND Spinal cord lesions is one of the predominant characteristics in patients with neuromyelitis optica spectrum disorders (NMOSD). Interestingly, mounting evidence indicates that spinal cord atrophy (SCA) is one of common clinical features in multiple sclerosis (MS) patients, and correlates closely with the neurological disability. However, Clinical studies related to the SCA aspects of...
متن کاملChronic neuropathic pain severity is determined by lesion level in aquaporin 4-antibody-positive myelitis.
IMPORTANCE Chronic, intractable neuropathic pain is a common and debilitating consequence of neuromyelitis optica spectrum disorder (NMOSD) myelitis, with no satisfactory treatment; few studies have yet to explore its aetiology. OBJECTIVE To establish if myelitis-associated chronic pain in NMOSD is related to the craniocaudal location of spinal cord lesions. METHOD (1) Retrospective cohort ...
متن کاملLongitudinally extensive transverse myelitis with pulmonary tuberculosis
Rationale: Longitudinally extensive transverse myelitis (LETM) is characterized by contiguous inflammatory lesions of spinal cord extending to ≥3 vertebral segments. The etiology of LETM is complicated, including various infection, autoimmune disease, and so on. Neuromyelitis optic spectrum disorder (NMOSD) is the most common cause of LETM. Several case reports have suggested the associations b...
متن کاملP9: Cervical Spinal Cord Extraction in Patients with Multiple Sclerosis Using Magnetic Resonance Imaging for Measuring Cross-Sectional Area
Multiple sclerosis (MS) refers to the lesions that accumulate in the brain and spinal cord. Magnetic resonance imaging (MRI) is the most sensitive and versatile modality used to show changes in the tissues over time. There has been significant interest in evaluating the relationship between the brain atrophy and disease progression rather than the spinal cord atrophy. The cervical spinal cord h...

OBJECTIVE To compare the motor recovery following transverse myelitis in pediatric patients with and without spinal cord atrophy. METHOD From January 1995 through December 2009, twenty children (8 boys and 12 girls with an onset at 5.7±3.8 years) that were diagnosed with transverse myelitis at a Children's Hospital in Korea, and undertaken an initial and follow-up spine magnetic resonance ima...
