Early initiation of steroid pulse therapy for neuromyelitis optica in an emergency room setting.

CASE: A 40-year-old man presented to the emergency room with visual impairment, dysesthesia of lower legs, and urinary retention. Two days before admission, he was consulted to the neurology department due to bilateral optic neuritis and scheduled the magnetic resonance imaging of spine. However, the urinary retention deteriorated acutely and he came to the emergency room. On arrival, the plain magnetic resonance image of his spine showed diffuse hyperintensity signals of the spinal cord in T2-weighted images. He was diagnosed with neuromyelitis optica and steroid pulse therapy was initiated.

OUTCOME: We began treatment immediately in the emergency room, cooperating with the neurology team. After admission, plasmapheresis was added for his fluctuating symptoms. On hospital day 7, he was discharged without complication.

CONCLUSION

It is important to understand the various clinical manifestations of neuromyelitis optica. In emergency settings, immediate steroid therapy is necessary for better outcomes.
