Abstract
Dengue virus (DENV) causes immune-mediated diseases. Neurological involvement represents a severe condition that is rarely observed in DENV-1 infection. Neuromyelitis optica (NMO)/NMO spectrum disorders (NMOSD) are idiopathic immune-mediated demyelinating syndromes of the central nervous system. We report a 17-year-old female with oligosymptomatic DENV-1 viremia, diagnosed as NMOSD. Magnetic resonance imaging showed spinal cord and brainstem lesions. Antibody for aquaporin 4 was negative. DENV-1 RNA infection was detected by serial RT-PCR and confirmed by phylogenetic analysis in serum. Although there are some reports of NMO post-dengue infection, there are not any published accounts of NMOSD with coexistent and persistent DENV-1 infection.
