Ultrasonography of Hands and Wrists in the Diagnosis of Complications of Chikungunya Fever.

The purpose of this series was to describe the ultrasonographic and radiographic manifestations of changes to the hands and wrists in 50 patients with chronic musculoskeletal symptoms secondary to Chikungunya fever during the 2016 outbreak that occurred in Rio de Janeiro, Brazil. Most of the plain radiographs were normal (62%). The most common ultrasonographic findings were small joint synovitis (84%), wrist synovitis (74%), finger tenosynovitis (70%), and cellulitis (50%). In most cases, power Doppler did not show an increase in synovial vascular flow. The plain radiographs showed no specific findings, whereas the ultrasound images revealed synovial compromise and neural thickening.

Ultrasound of ankles in the diagnosis of complications of chikungunya fever.

OBJECTIVE: To describe the main ultrasound findings of chikungunya fever in the ankle. MATERIALS AND METHODS: This was a cross-sectional observational study involving 52 patients referred to the Hospital Universitário Pedro Ernesto and presenting with clinical and biochemical evidence of chikungunya fever. The examinations were performed by a radiologist with more than 20 years of experience in ultrasound. RESULTS: The predominant gender was female (in 88.5%), and the mean age was 58.4 years. The majority (61.5%) of the patients came from the northern part of the city of Rio de Janeiro, and 46.2% were using corticosteroids to treat inflammatory symptoms. The most common alterations observed by ultrasound were joint effusion (in 69.2%), tenosynovitis (in 59.6%), cellulitis (in 46.2%), Kager's fat pad thickening (in 29.9%), myositis (of the soleus or flexor hallucis longus muscle) (in 17.3%), retrocalcaneal bursitis (in 5.8%), tendon ruptures (in 3.8%), and increased vascular flow on power Doppler (in 3.8%). CONCLUSION: Signs of synovitis and tenosynovitis were the main ultrasound findings in a predominantly female population with a mean age of 58.4 years. Further studies are needed in order to define the role of ultrasound in the follow-up of such patients.

OBJETIVO: Descrever os principais achados ultrassonográficos da febre chikungunya no tornozelo. MATERIAIS E MÉTODOS: Estudo transversal e observacional com 52 pacientes encaminhados ao Hospital Universitário Pedro Ernesto com quadros clínico e laboratorial compatíveis com febre chikungunya. Os exames foram realizados por um radiologista com mais de 20 anos de experiência no método. RESULTADOS: Houve predomínio do sexo feminino (88,5%) e média de idade dos pacientes de 58,4 anos. A maioria dos doentes (61,5%) era proveniente da zona norte da cidade do Rio de Janeiro e fazia uso de esteroides (46,2%) para o tratamento dos sintomas inflamatórios. As alterações ultrassonográficas mais comuns foram: derrame articular (69,2%), tenossinovites (59,6%), celulite (46,2%), espessamento da gordura de Kager (29,9%), miosite (sóleo e/ou flexor longo do hálux) (17,3%), bursite retrocalcânea (5,8%), roturas tendíneas (3,8%) e hiperfluxo vascular pelo Doppler de amplitude (3,8%). CONCLUSÃO: Predominaram os sinais ultrassonográficos de sinovite e tenossinovite numa população majoritariamente do sexo feminino e com idade média de 58,4 anos. Sugere-se a realização de outros estudos para definição do papel da ultrassonografia no acompanhamento desses doentes.
