Background: Chikungunya is an infection caused by an RNA-virus and transmitted from primates to humans by Aedes aegypti and Aedes albopictus mosquitoes. Usually, it causes fever, widespread exanthema, myalgia and severe diffuse joints pain but may present several complications, such as neurological manifestations.

Case presentation: We describe a case of a 38-year-old man with diagnostic confirmation of chikungunya virus infection based on the clinical manifestations of the disease and positivity of the serological tests. He has evolved with peripheral mononeuropathy confirmed by clinical examination and electroneuromyography.

Conclusion: Peripheral neuropathy may be a neurological complication of CHIKV infection and to the best of our knowledge this is the first Brazilian case of peripheral mononeuropathy secondary to CHIKV infection.
