Abstract
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.
