Neuromyelitis Optica (NMO) can have atypical presentations like hiccups, vomiting, etc. which is classically described as the area postrema syndrome. Here we report a case of a 39 year old male patient who presented with features of Trigeminal Autonomic Cephalalgia (TAC). MRI spine showed long segment myelitis. Diagnosis of NMO was confirmed by a positive Anti aquaporin 4 antibody assay. TACs are a rare group of headache disorders characterized by severe unilateral headache in the V1 distribution of the trigeminal nerve and autonomic symptoms. This presentation in NMO is hitherto unreported in literature.
