Abstract
We reported the case of 5-year-old boy initially suspected of having retropharyngeal abscess due to fever, cervical lymph node swelling, and CT imaging. The confirmed diagnosis of Kawasaki disease was made by magnetic resonance imaging with contrast agent. Kawasaki disease should be considered in older children who have a retropharyngeal abscess on CT scan in addition to fever, cervical lymphadenopathy, and especially when antibiotics have no effect on the clinical symptoms. In addition, magnetic resonance imagings with a contrast agent should be performed.
