Coronary Artery Dilatation in Viral Myocarditis Mimics Coronary Artery Findings in Kawasaki Disease.

Coronary artery (CA) dilatations are typical to Kawasaki disease (KD) in the pediatric population. CA involvement is a useful feature to help establish the diagnosis of KD. Since myocarditis is omnipresent in the acute phase of KD, we sought to investigate whether viral myocarditis may cause CA dilatation.

Coronary artery dilatation and vasculitis in a case of rabies: similarity with Kawasaki disease?

A 9-year-old boy died of rabies complications. We report the unusual combination between rabies, coronary dilatation on echocardiography and coronary vasculitis documented upon autopsy. In the search for the etiological agent of Kawasaki disease, we suggest that a viral infection with potential antigenic similarities to rabies virus should be entertained.
