Abstract:
Chikungunya virus was initially thought to be a non-neurotropic virus, but recently neurological complications have been reported in patients with chikungunya virus infection. Here, we report a rare case of stimulus-sensitive myoclonus following chikungunya meningoencephalitis. The cranial MRI scan of the patient was normal, the cerebrospinal fluid contained 200 lymphocytes/mm(3), and the serum immunoglobulin M ELISA was positive for chikungunya. The patient improved completely after 1 month of treatment. This case study illustrates that chikungunya virus should also be considered in a febrile patient with myoclonus, especially in an endemic area.
