Abstract

The dengue virus, a member of the family Flaviviridae, is transmitted by Aedes mosquitoes and causes a viral disease known as dengue fever that is prevalent in tropical and subtropical regions. It is estimated that there are 100-400 million new infections every year, with underreporting due to limited surveillance systems. The presentation ranges from asymptomatic to dengue shock syndrome. Brazil is now facing an endemic of dengue, having seen a significant seasonal increase of over 4.5 million in the number of probable cases reported. Imaging exams such as ultrasound, computed tomography, and magnetic resonance imaging are crucial for detecting complications of dengue, aiding in the clinical management and differential diagnosis, especially in severe cases. The aim of this study was to illustrate the radiological findings of dengue, focusing on emergency and critical care settings.
