摘要
Neuromyelitis optica spectrum disorder(NMOSD)is a humoral immune-mediated inflammatory demyelinating disease of the central nervous system with an unclear pathogenesis,often associated with autoimmune diseases such as systemic lupus erythematosus and dry syndrome.The pathology of the disease shows demyelinating changes and axonal damage,and the lesions mostly involve the optic nerve and spinal cord,and the last region of the medulla oblongata,thalamus,paraventricular,and other sites with high aquaporin-4 expression can also be involved.The clinical manifestations are closely related to the location of the lesion,with common symptoms such as optic neuritis,acute myelitis,and intractable eruption,and most patients have recurrent episodes that can leave sequelae such as visual impairment and urinary and bowel disorders.However,a few patients present with less common symptoms,which can easily be missed or misdiagnosed,delaying the diagnosis and treatment of the disease.In this paper,we report the case of a middle-aged female patient with the first symptoms of optic neuritis who developed seizures after 2 months.After completing relevant tests,cerebrospinal fluid and serum anti-aquaporin-4 antibodies were positive,and NMOSD with symptomatic epilepsy was considered.Seizures did not recur after hormone therapy was given again.The purpose of this report is to improve awareness and diagnosis of NMOSD among clinicians.
