Neuromyelitis optica spectrum disorder post-COVID-19 infection: A rare case report from Northeast India.

ABSTRACT

Multiple sclerosis and neuromyelitis optica spectrum disorder may be seen in the acute setting of coronavirus disease 2019 (COVID-19) infection or even post-recovery. Such patients may present with optic neuropathy along with weakness in the back and lower limbs. Ascending paralysis can present with respiratory distress in acute COVID-19 infection and may even prove to be fatal. We report a unique case of a 16-year-old female with past history of COVID-19 infection having optic neuropathy, and radioimaging showing demyelinating plaques in the central nervous system with spinal cord edema. Serology showed positivity for rheumatoid arthritis, and the patient was managed with steroids and rituximab.
