Conclusion:
COVID-19-associated neurological manifestations are widely reported,
with some rare instances of anti-MOG syndrome in coexistence with
SARS-CoV-2 infection. We report the first case of concurrent NMOSD and
IIH in the context of COVID-19 infection. While the propensity for
triggering autoantibody production and thrombophilic disorders is
prevalent in COVID-19, physicians and neurologists must be vigilant with
low threshold to further investigate the possibility of secondary
idiopathic intracranial hypertension and demyelinating disorders in
patients presenting with headache and decreased visual acuity following
recent COVID-19 infection.
