Neuro-Chikungunya: Acute Transverse Myelopathy Associated with Chikungunya Virus Infection.

ABSTRACT

Chikungunya is an arboviral infection caused by Chikungunya virus, an RNA virus from Togaviridae family.1 The disease manifests as fever, rash and characteristically, with arthralgia.1 Chikungunya is strongly believed to have neurotropism but has not been well studied like other neurotropic arboviruses.2 Encephalitis appears to represent the most common clinical manifestation6 and occurs either simultaneously or within few days of onset of systemic symptoms, during the period of viremia. A delay of more than two weeks has been reported with other complications like myelitis, Guillian Barre syndrome and optic neuritis. This case describes the clinical, serological, neuroimaging and CSF findings of Chikungunya induced acute transverse myelitis in a 13 years old male patient who responded to steroid treatment. It is a relatively unknown and very rare complication of Chikungunya virus infection during outbreak of Chikungunya infection in September 2016.
