Magnetic resonance imaging (MRI) showed predominant lesions in the optic tracts, optic chiasm, and hypothalamus. Cerebrospinal fluid analysis revealed elevated protein level, and lymphocytic pleocytosis. Neurophysiological studies disclosed a demyelinating sensorimotor polyneuropathy. Serum anti- Mycoplasma pneumoniae immunoglobulin (Ig)M, anti-GM1 IgG, and anti-AQP4 IgG were positive. This case, which is remarkable for post-infectious meningoencephalitis-like onset, MRI picture, and dysimmunity to central and peripheral nervous system autoantigens, underpins the pivotal diagnostic role of anti-AQP4-IgG, and expands the list of clinico-pathological findings that can associate with neuromyelitis optica spectrum disorders.<\/jats:p>","DOI":"10.1177\/1352458514524294","type":"journal-article","created":{"date-parts":[[2014,2,20]],"date-time":"2014-02-20T21:52:47Z","timestamp":1392933167000},"page":"246-248","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Meningoencephalitis-like onset of post-infectious AQP4-IgG-positive optic neuritis complicated by GM1-IgG-positive acute polyneuropathy"],"prefix":"10.1177","volume":"21","author":[{"given":"Luana","family":"Benedetti","sequence":"first","affiliation":[{"name":"Department of Neurology, Osp.
