title: Autoimmune myelopathy associated with collapsin response-mediator protein-5 immunoglobulin G.
abstract: Several autoimmune myelopathies are recognized clinically. We describe 57 patients in whom serological evaluation for myelopathy of uncertain cause demonstrated collapsin response-mediator protein 5 IgG. Most had spinal imaging and cerebrospinal fluid abnormalities and insidiously progressive presentation; some had acute monophasic or relapsing myelopathy. Initial diagnoses included multiple sclerosis, transverse myelitis, and unspecified neurodegenerative myelopathy. Most were smokers; neoplasia was discovered in 68% (most commonly small-cell lung carcinoma and after collapsin response-mediator protein-5 IgG detection). Collapsin response-mediator protein-5 autoimmune myelopathy and occult neoplasia are important considerations in patients with insidiously progressive myelopathy, especially with known cancer risk.
