[Kawasaki disease in Sicily: description of the first case with giant coronary aneurysm].

A case of Kawasaki disease with early development of giant coronary artery aneurysm is reported. The delay in the diagnosis and consequently in the use of correct therapy has conditioned the outcome of the illness. We don't know the predictive factors of cardiac complications, but steroid treatment in our patient probably had an important role in the cardiac damage. The use of echocardiography in the evaluation of coronary aneurysm has confirmed the sensitivity, specificity and predictive value of this technique in detecting cardiac lesions.
