This study describes a young girl who presented with involuntary weight loss, spontaneous vomiting and behavioural change. Imaging confirmed hypothalamic and brainstem involvement. Routine investigations (including cerebrospinal fluid analysis and neuromyelitis optica IgG) were unhelpful. Biopsy of the hypothalamic lesion implicated an aggressive inflammatory aetiology. There was a response to conventional immunosuppression, while a further relapse responded to plasma exchange. She died 21 months after presentation. Postmortem examination was highly suggestive of neuromyelitis optica, which was subsequently confirmed following the identification of aquaporin 4 antibodies.

The patient is a 68-year-old Japanese woman. She was admitted to our hospital due to continuous hiccups and vomiting episodes for more than one week. On examinations, muscle strength in her right lower limb was slightly decreased, and pyramidal tract signs were positive bilaterally. The fluid attenuated inversion recovery imaging of the brain showed lesions in the dorsal and lateral medulla. Serum anti-aquaporin 4 antibody was positive. We then diagnosed the patient with neuromyelitis optica spectrum disorder (NMOSD). Severe orthostatic hypotension (OH) was determined. While hiccups and vomiting improved gradually, OH lasted for more than three weeks. OH improved after administration of intravenous methylpredonisolone-pulse therapy. In this case, the lesion in the dorsal medulla might be responsible for OH. We considered that OH might be one of the symptoms of NMOSD.

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.

Vomiting and hiccups can be the manifestations of numerous systemic and neurological illnesses. Intractable nausea, vomiting and hiccups (INH) are reported as possible initial manifestations of neuromyelitis optica (NMO), but not correctly identified. Awareness of these atypical presentations is conducive to NMO early diagnosis and proper treatment to prevent further disability. In this paper, 12 NMO were reported, whose intractable vomiting and hiccups were the sole manifestations of the first attack and other attacks involving spinal cord and optic nerves developed later. All the patients were women and serum aquaporin 4 antibody (AQP4-Ab) of 83% patients was positive. MRI of 50% patients showed T2-weighted imaging/fluid attenuated inversion recovery hyperintensity which were longitudinally extensive transverse myelitis or linear signal changes. Sixty-seven percent of patients had medulla lesions, in which dorsomedial and area postrema were involved.

A 17-year-old girl presented with intractable vomiting due to area postrema involvement in the first presentation of seronegative neuromyelitis optica (NMO). During the course of her illness, she developed mild hyponatremia, and magnetic resonance imaging revealed abnormalities consistent with the co-occurrence of osmotic demyelination syndrome (ODS). This combination of imaging features is novel, and this case expands the spectrum of brain abnormalities seen in NMO and NMO spectrum disorders. It was suspected that NMO may predispose to ODS by causing astrocyte dysfunction involving aquaporin 4 water channels, which are implicated in both conditions.
