Is it Kawasaki disease?
Atypical cases of KD are common (up to 10% of the total) and the diagnosis should be considered without the full complement of diagnostic criteria. The risk of coronary dilation is high if IVIG is not given. Administration of IVIG is effective at preventing aneurysms, if given early. The high-risk groups for coronary artery disease are infants younger than 6 months of age and older children with very high platelet counts, high ESR and fever persisting for more than 2 weeks.
