Comprehensive evaluation of Kawasaki disease with electrocardiogram-gated cardiac multidetector computed tomography.

We present a case of a young woman with Kawasaki disease who was comprehensively evaluated by electrocardiograph-gated cardiac multidetector computed tomography (MDCT). MDCT disclosed 3-vessel giant coronary arterial aneurysms and associated focal apical septal myocardial pathology. This was characterized by an early enhancement defect, myocardial thinning, and hypokinesia. These findings are likely due to focal ischemic insult resulting from distal embolization of thrombus material from the giant proximal right coronary arterial aneurysms. This case illustrates the full capabilities of MDCT in the comprehensive evaluation of Kawasaki disease.
