Neuromyelitis Optica (previously called Devics disease) is an autoimmune-induced demyelinating disorder of the central nervous system that primarily affects the optic nerves and spinal cord. This manuscript presents a case of a 28-yearold female patient who clinically presented with acute lower extremity weakness and numbness associated with unilateral impairment of vision. Later in the course of the disease, magnetic resonance imaging of the cervico-thoracic spine showed multi-level abnormal non-enhancing and enhancing lesions from levels C3 to T8 levels which were identified to be combined transverse myelitis and cord syrinx. An anti-aquaporin-4 receptor antibody was obtained and yielded to be seropositive. Given the patients clinical manifestations, combined with imaging and laboratory examinations, led to a diagnosis of Neuromyelitis Optica (NMO). The patient was managed with high-dose steroids. The significant discovery of anti-aquaporin-4 antibodies served as a key factor in the NMO immunopathogenesis. It is currently regarded as a specific biomarker of the diagnostic process, making it distinguishable from multiple sclerosis. This case highlights the mechanism of formation of a fluid-filled syrinx-like cavity in the cord in the setting of Neuromyelitis Optica.
