A 22-year-old woman presented with double vision that she had experienced since an infection 2 weeks previously. A neurological examination showed limited bilateral eye abduction, mimicking Miller Fisher syndrome. However, T2-weighted magnetic resonance imaging of her brain revealed hyperintense areas in the tegmentum of the pons, including the abducens nucleus, and her serum anti-aquaporin-4 a...
Diagnostic criteria for neuromyelitis optica (NMO) state that there should be no active disease outside the optic nerves and spinal cord. However, several cases have been described with symptomatic brain involvement. We describe an autopsy case of a patient with NMO and symptomatic involvement of the brain. The histopathology of the brain lesions is typical for NMO, with extensive macrophage in...
ON is an immune‐mediated inflammation of the optic nerve, which could be the initiated symptom of multiple sclerosis (MS) or neuromyelitis optica (NMO). Bilateral simultaneous ON with long enhanced optic nerve lesions in magnetic resonance imaging (MRI) was considered as features of NMO spectrum disorders (NMOSDs). However, comprehensive review of the current literature showed little evidence o...
We describe three unrelated patients presenting with a spinal cord syndrome and neuroimaging features consistent with multiple sclerosis (MS). All harbored a pathogenic OPA1 mutation. Although the neurological phenotype resembled neuromyelitis optica (NMO), anti-aquaporin 4 antibodies were not detected and the disorder followed a slow progressive course. The coincidental occurrence of OPA1 muta...
I report a 45-year old woman who had a history of neuromyelitis óptica (NMO). She was admitted by bilateral blindness and mydriasis, as well as tetraparesia. The visual evoked potential revealed absence of waves in both eyes. For this reason, she received an omental transplantation on the optic chiasm and left temporal lobe. Three days after surgery, she presented motor improvement in her limbs...
Neuromyelitis optica spectrum disorder (NMOSD) associated with aquaporin-4 antibody (AQP4-Ab) predominantly targets the optic nerve and spinal cord and is characterized by frequent relapses and accrual of irreversible disability. Variations in clinical course may include an initial or predominant involvement in extra spinal/optic nerve locations and a benign course marked by mild attacks and mi...
Neuromyelitis optica and multiple sclerosis: Seeing differences through optical coherence tomography
Neuromyelitis optica (NMO) is an inflammatory autoimmune disease of the central nervous system that preferentially targets the optic nerves and spinal cord. The clinical presentation may suggest multiple sclerosis (MS), but a highly specific serum autoantibody against the astrocytic water channel aquaporin-4 present in up to 80% of NMO patients enables distinction from MS. Optic neuritis may oc...
Anti-myelin oligodendrocyte (MOG)-positive cases have a variable clinical presentation. MOG autoantibodies are associated with acute disseminated encephalomyelitis, multiple sclerosis, clinically isolated syndrome, neuromyelitis optica, optic neuritis, and transverse myelitis. Our patient had bilateral neuritis tetraparesis. Cranial magnetic resonance imaging (MRI) showed leptomeningeal contras...
Neuromyelitis optica (NMO) is a rare autoimmune disease affecting the optic nerves and spinal cord. In the majority of NMO patients anti-aquaporin-4 antibodies (AQP4-IgG) are detected. Here we assessed a nationwide incidence of AQP4-IgG-seropositive NMO spectrum disorders (NMOSD) in the Netherlands based on results of one central laboratory. Data were collected since the introduction of the hig...
