Autoantibodies targeting aquaporin 4 (AQP4) water channels are a sensitive and specific biomarker for neuromyelitis optica spectrum disorder (NMOSD). Presence of AQP4 antibodies distinguishes NMOSD from multiple sclerosis. We present our experience with an anti-AQP4 antibody-positive patient

Myelitis of the spinal cord is an uncommon presentation of disseminated coccidioidomycosis. Most infected patients present subclinically, but patients, especially those who are immunocompromised, may progress to disseminated disease. We present a 50-year-old immunocompetent patient with no

We report a case of transverse myelitis in an immunocompetent host with an atypical long onset of symptoms. A 56-year-old man was admitted to the hospital reporting 5 months of progressive ascending lower extremity weakness and numbness, inability to walk, bowel incontinence,urinary retention and

Neuromyelitis optica (NMO) is a disease of central nervous system, characterized by demyelination and axonal damage mostly involving optic nerves and spinal cord. Usually these patients present with symptoms related to optic neuritis or myelitis with a typical relapsing course. Some patients present

Neuromyelitis optica (Devic's disease) is a chronic autoimmune disease associated with the production of anti-bodies to aquaporin-4 (AQP4). Area postrema lesions is the third, after optic neuritis and myelitis, syndrome of opticomyelitis-related disorders. Clinical symptoms of this disorder include

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

Longitudinally extensive transverse myelitis (LETM) is a characteristic feature of Neuromyelitis Optica (NMO), but it can also occur in several other inflammatory diseases of the central nervous system (CNS). An IgG autoantibody that binds to aquaporin-4 (AQP4), the predominant water channel of the

Neuromyelitis optica (NMO) is an inflammatory demyelinating disease with a poor prognosis that is characterized by inflammatory optic neuritis and myelitis. Although it is commonly misdiagnosed as multiple sclerosis (MS), distinguishing NMO from MS is important, as therapeutic approaches approved

A 45-year-old female was positive for anti-aquaporin-4 antibody with disturbance of consciousness, respiratory failure, and ophthalmoplegia associated with extensive brain stem involvement with intractable hiccup and nausea as an initial manifestation. Her level of consciousness and state of

OBJECTIVE Short transverse myelitis (STM; <3 vertebral segments) is considered noncharacteristic of neuromyelitis optica (NMO) spectrum disorders (NMOSDs). Nonappreciation of the potential for STM to occur in NMOSD may lead to increased disability from delay in diagnosis and appropriate

OBJECTIVE To characterize the neuropathologic features of neuromyelitis optica (NMO) at the medullary floor of the fourth ventricle and area postrema. Aquaporin-4 (AQP4) autoimmunity targets this region, resulting in intractable nausea associated with vomiting or hiccups in NMO. METHODS This

Intractable hiccup and nausea (IHN) was found in eight of 47 cases of relapsing neuromyelitis optica (NMO) (17%) but in none of 130 cases of multiple sclerosis (MS). IHN resolved with methylprednisolone. In six cases, MRI detected linear medullary lesions involving the pericanal region, the area

OBJECTIVE Neuromyelitis optica is associated with severe neurodisability if not recognized and treated promptly. Several autoimmune disorders are associated with this condition and may vary in their presentation. It is essential that clinicians are aware of the uncommon presenting features of

OBJECTIVE Antibodies against the water channel protein aquaporin (AQP)-4 cause a spectrum of inflammatory, demyelinating, central nervous system disorders called neuromyelitis optica spectrum disorders (NMOSDs); these primarily affect the optic nerves and spinal cord but also the brain. Symptoms of

BACKGROUND Intractable hiccup and nausea (IHN) are unique symptoms in neuromyelitis optica (NMO). Recent studies have strongly suggested that the pathogenesis of NMO is closely associated with anti-aquaporin-4 (AQP4) antibody. However, clinical implications of IHN and the relationship with anti-AQP4
