Kawasaki disease (KD) is an acute and usually self-limiting medium vessel vasculitis of childhood that has a predilection to involve the coronary arteries. It is characterized by the sequential appearance of a constellation of clinical features [1]. However, none of these clinical findings is, in itself, pathognomonic of KD. Many of these clinical features can, in fact, be seen in other common febrile illnesses of children. It is for this reason that the diagnosis of KD is often considered to be a clinical challenge [2]. Approximately 15-25% of untreated patients may go on develop coronary artery abnormalities (CAAs) and this remains the major cause of morbidity, and occasional mortality, in KD [3].
