Acute transverse myelitis following dengue virus infection

Abstract

The spinal cord is infrequently affected following dengue virus infection. We report a case of transverse myelitis that developed 2 weeks after acute dengue infection and review the literature to elucidate the pathogenesis of spinal cord involvement in dengue infection. We postulate that temporal factors may play a role in the different clinical manifestations, i.e. that acute parainfectious dengue infection presents with flaccid paralysis, whereas late-stage (postinfectious) dengue infection, presents with spastic weakness. Further studies need to be performed to elucidate the mechanisms of spinal neurological damage in dengue.
