INTRACTABLE VOMITING AS THE INITIAL PRESENTATION OF NEUROMYELITIS OPTICA SPECTRUM DISORDER: A CASE REPORT

Abstract

We present our experience with an anti-AQP4 antibody-positive patient diagnosed with NMOSD who complained of intractable nausea and vomiting, not restricted to optic neuritis or acute myelitis during the first attack. Her symptoms partially resolved after appropriate therapy with therapeutics plasma exchange, intravenous methylprednisolone and oral prednisolone and follow up to azathioprine 50 mg. Through this case, we hope to draw attention to an unusual neurological presentation of NMOSD which should be included in the differential diagnosis of intractable nausea and vomiting.
