The anti-NF186 antibody is a recently discovered antibody associated with central or peripheral demyelination. The co-occurrence of these two antibodies has not been reported. Herein, we report a case with anti-CV2\/CRMP5 and anti-NF186 antibodies in a 57-year-old male presenting with progressive numbness and weakness in his four limbs. At first admission, the spinal cord MRI showed a cervical cord demyelinating lesion and electrophysiological examination showed a mixed demyelinating and axonal polyneuropathy. Anti-CV2\/CRMP5 and anti-NF186 antibodies were both detected in his serum. Initially, the patient showed a positive response to IVIG and glucocorticoid treatment. However, the syndrome relapsed and mass lesions in lung and mediastinum were detected at second admission. This time the anti-NF186 antibody was not detected but the anti-CV2\/CRMP5 antibody was still present. IVIG and glucocorticoid treatment was no longer effective. This case illustrated that paraneoplastic syndrome should be considered when diagnosing patients with central and peripheral demyelination, and that the anti-NF186 antibody may help distinguish a subset of patients who can benefit from immunomodulatory treatments.<\/jats:p>","DOI":"10.3390\/brainsci13030374","type":"journal-article","created":{"date-parts":[[2023,2,22]],"date-time":"2023-02-22T02:31:55Z","timestamp":1677033115000},"page":"374","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Paraneoplastic Syndrome Presenting Combined Central and Peripheral Demyelination Associated with Anti-CV2\/CRMP5 and Anti-NF186 Antibodies: A Case Report"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2350-5680","authenticated-orcid":false,"given":"Bingyou","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Neurology, Huashan Hospital, Fudan University, 12 Middle Wulumuqi Road, Jingan, Shanghai 200040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Neurology, Huashan Hospital, Fudan University, 12 Middle Wulumuqi Road, Jingan, Shanghai 200040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongsheng","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Neurology, Huashan Hospital, Fudan University, 12 Middle Wulumuqi Road, Jingan, Shanghai 200040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chong","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Neurology, Huashan Hospital, Fudan University, 12 Middle Wulumuqi Road, Jingan, Shanghai 200040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Neurology, Huashan Hospital, Fudan University, 12 Middle Wulumuqi Road, Jingan, Shanghai 200040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"196","DOI":"10.1016\/j.autrev.2011.05.012","article-title":"Autoimmune disorders affecting both the central and peripheral nervous system","volume":"11","author":"Kamm","year":"2012","journal-title":"Autoimmun.
