Case Report: Neuromyelitis Optica Spectrum Disorder With Progressive Elevation of Cerebrospinal Fluid Cell Count and Protein Level Mimicking Infectious Meningomyelitis: A Diagnostic Challenge.

Front Immunol 2022 19;13:864664. Epub 2022 May 19.

Department of Neurology, Tongde Hospital of Zhejiang Province, Hangzhou, China.

Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune-mediated idiopathic inflammatory demyelinating disease with a typical clinical presentation of optic neuritis, acute myelitis, and area postrema syndrome. Most NMOSD patients are seropositive for disease-specific and pathogenic aquaporin-4 (AQP4) antibodies, which are key markers for the NMOSD diagnosis. Herein, we report an atypical case of a 41-year-old man who complained of intractable hiccups and vomiting at disease onset, followed by fever, headache, back pain, progressive paresthesia, and weakness of extremities later on.

Clinical and Radiological Features of Myelin Oligodendrocyte Glycoprotein-Associated Myelitis in Adults.

J Clin Neurol 2022 May;18(3):280-289

Department of Neurology, Research Institute and Hospital of National Cancer Center, Goyang, Korea.

Antibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have recently been established as a biomarker for MOG-antibody-associated disease (MOGAD), which is a distinct demyelinating disease of the central nervous system. Among the diverse clinical phenotypes of MOGAD, myelitis is the second-most-common presentation in adults, followed by optic neuritis. While some features overlap, there are multiple reports of distinctive clinical and radiological features of MOG-IgG-associated myelitis, which are useful for differentiating MOGAD from both multiple sclerosis and neuromyelitis optica spectrum disorder.

Newly diagnosed multiple sclerosis in a patient with ocular myasthenia gravis: A case report.

Medicine (Baltimore) 2022 Feb;101(8):e28887

Department of Neurology, Jeonbuk National University Medical School and Hospital, Jeonju, South Korea.

Rationale: Patients with myasthenia gravis may also have comorbid autoimmune diseases. Since both myasthenia gravis and neuromyelitis optica spectrum disease are mediated by antibodies, they are likely to occur together. However, since multiple sclerosis is an autoimmune disease that is not mediated by a specific antibody, it has fewer immune mechanisms in common with myasthenia gravis than neuromyelitis optica spectrum disease.
