Leidersnaider CL, Vaz JLP, Sztajnbok FR, Gonçalves MT, Mogami R. Multimodal imaging of psoriatic arthritis triggered by Chikungunya fever. Int J Case Rep Images 2021;12:101229Z01CL2021.ABSTRACT
Chikungunya fever (CF), caused by the Chikungunya virus (CHIKV), is an arboviral disease transmitted by infected Aedes mosquitoes found worldwide. Although CF may trigger chronic arthritis, there are still few reports of patients who have progressed to psoriatic arthritis (PsA). We describe the clinical and ultrasound (US) and magnetic resonance imaging (MRI) findings of the wrist and hands of a 49-year-old man who had peripheral PsA triggered by CHIKV. He had scaly, itchy scalp lesions three months after the diagnosis of CF. The patient had classic synovitis and tenosynovitis secondary to CF. The persistence of inflammatory disease with signs of enthesitis and dactylitis on magnetic resonance imaging (MRI) and US, family history and appearance of skin lesions on the scalp strongly suggest post-CF PsA. Viral infections can be a triggering factor for several diseases with chronic arthritis, such as PsA. Imaging exams are essential methods for both diagnosis and the monitoring of treatment.
