title: Inflammatory, vascular, and infectious myelopathies in children.
abstract: Acute nontraumatic myelopathies of childhood include inflammatory, infectious, and vascular etiologies. Inflammatory immune-mediated disorders of the spinal cord can be categorized as idiopathic isolated transverse myelitis, neuromyelitis optica, and multiple sclerosis. In recent years, human T-cell lymphotropic virus type 1, West Nile virus, enterovirus-71, and Lyme disease have been increasingly recognized as infectious etiologies of myelopathy, and poliomyelitis remains an important etiology in world regions where vaccination programs have not been universally available. Vascular etiologies include vasculopathies (systemic lupus erythematosus, small vessel primary angiitis of the central nervous system), arteriovenous malformations, and spinal cord infarction (fibrocartilaginous embolism, diffuse hypoxic ischemia-mediated infarction). Vascular myelopathies are less common than inflammatory and infectious myelopathies, but are more likely to lead to devastating clinical deficits. Current therapeutic strategies include acute anti-inflammatory treatment and rehabilitation. Stem cell transplantation, nerve graft implantation, and stimulation of endogenous repair mechanisms represent promising strategies for spinal cord repair.
