A Confused Case Diagnosed as Cerebral Infarction or Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease.

In order to discuss the clinical and MRI features, diagnosis, and prevention of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), we reported an adult case of MOG antibody-related disease misdiagnosed as cerebral infarction. This patient's first clinical symptom was limb weakness, that different from previous reports of MOG antibody-related diseases, such as brainstem encephalitis, neuromyelitis optical, and transverse myelitis. The main treatment plan is high-dose corticosteroid therapy combined with immunoglobulin therapy. This case indicated that some MOGAD patients lack of specificity in the clinical manifestations and imaging perhaps would be misdiagnosed as cerebral infarction, encephalitis, immune peripheral neuropathy, MS, NMOSD, and other diseases. For patients with atypical clinical manifestations or imaging, it is especially important to take antibody detection as early as possible to make correct diagnosis and active treatment in time to avoid disability.
