Coronary Artery Dilation in Children with Febrile Exanthematous Illness without Criteria for Kawasaki Disease.

Background: Coronary dilatation is the most important complication of Kawasaki disease (KD) and, in addition to some clinical characteristics, is common to KD and febrile exanthematous illnesses (FEIs).

Objective: To assess whether children with FEI, who do not meet the criteria for KD, have changes in coronary arteries dimensions.

Methods: Echocardiography was performed within the first two weeks of the disease in patients < 10 years with fever and exanthema without other KD criteria.
