Materials and Methods: This was a cross-sectional observational study involving 52 patients referred to the Hospital Universit\u00e1rio 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.<\/jats:p>","DOI":"10.1590\/0100-3984.2016.0221","type":"journal-article","created":{"date-parts":[[2017,2,20]],"date-time":"2017-02-20T09:04:55Z","timestamp":1487581495000},"page":"71-75","source":"Crossref","is-referenced-by-count":11,"title":["Ultrasound of ankles in the diagnosis of complications of chikungunya fever"],"prefix":"10.1590","volume":"50","author":[{"given":"Roberto","family":"Mogami","sequence":"first","affiliation":[{"name":"Universidade do Estado do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o Luiz Pereira","family":"Vaz","sequence":"additional","affiliation":[{"name":"Universidade Federal do Estado do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y\u00eadda de F\u00e1tima Barcelos","family":"Chagas","sequence":"additional","affiliation":[{"name":"Universidade Federal do Estado do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Sperling","family":"Torezani","sequence":"additional","affiliation":[{"name":"Universidade do Estado do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9 de Almeida","family":"Vieira","sequence":"additional","affiliation":[{"name":"Universidade do Estado do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana C\u00e9lia Baptista","family":"Koifman","sequence":"additional","affiliation":[{"name":"Universidade do Estado do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasmin Baptista","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Universidade do Estado do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mirhelen Mendes de","family":"Abreu","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2017,2,20]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"151","DOI":"10.7883\/yoken.JJID.2015.063","article-title":"Chikungunya fever in Japan imported from the Caribbean Islands","volume":"69","author":"Imai K","year":"2016","journal-title":"Jpn J Infect Dis"},{"key":"ref2","first-page":"161","article-title":"Chikungunya fever.
