Abstract
Vomiting and hiccups can be due to peripheral or central causes. Neurological diseases causing vomiting and hiccups are due to lesions of medulla involving area postrema and nucleus tractus solitarius. Neuromyelitis optica (NMO) is one such disease which involves these structures. However refractory vomiting and hiccups as the presenting symptom of NMO is unusual. Here we report a patient with NMO in whom refractory vomiting and hiccups were the sole manifestation of the first attack. Diagnosis can be missed at this stage leading to delay in treatment and further complications. This case demonstrates the importance of considering NMO in any patient presenting with refractory vomiting and hiccups and with local and metabolic causes ruled out and linear medullary lesion on magnetic resonance imaging may indicate the diagnosis even when the classical clinical criteria are not met. Anti NMO antibody testing should be done and if positive appropriate treatment should be initiated to prevent further neurological damage.
