ABSTRACT
Abstract Objective:
To describe the main ultrasound findings of chikungunya fever in the ankle. Materials andMethods:
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.RESUMO
Resumo 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.
