Giant coronary aneurysm in adult Kawasaki disease: angiographic, 64-slice coronary MDCT and cardiac MRI appearances
Kawasaki disease is a small-to-medium-vessel vasculitis that preferentially affects infants and young children. This condition is rare in adults, and therefore the diagnosis can easily be missed in a patient presenting to a primary care clinic. We report an unusual case of a patient who presented with ventricular fibrillation on a background of adult Kawasaki disease.
To identify the advantages of using coronary multidetector computed tomography (MDCT) and cardiac magnetic resonance imaging (MRI) in diagnosing adult Kawasaki disease.
We studied a 52-year-old patient with Kawasaki disease using coronary angiography, cardiac MDCT and MRI.
Invasive coronary angiography demonstrated an occluded right coronary artery (RCA) and appearances suspicious for a calcified giant RCA aneurysm. The full extent of the aneurismal RCA was depicted with MDCT. Cardiac MRI revealed a chronic inferior segment myocardial infarction representing an arrhythmia substrate.
Our case highlights the increasing utility of contrast-enhanced cardiac MRI and MDCT in the diagnosis of this rare condition in adults.
