[Kawasaki disease in a young infant: difficulties for diagnosis and early complications].
We report 1 case of Kawasaki disease in young infant, featuring atypical presentation and severe outcome.


METHODS
A 3-month-old patient was admitted with initial cervical lymphadenitis, and lasting fever. He subsequently developed the classical manifestations of Kawasaki disease. Treatment with intravenous gamma globulins was successful only after a second perfusion. The early echocardiography revealed a coronary vasculitis, which progressed rapidly and was followed by complications as right coronary thrombosis, several aneurysms, and some others as exsudative enteropathy, aseptic meningitis and hepatitis.


CONCLUSIONS
Patients less than 6 months with Kawasaki disease are at increased risk of atypical presentation, severe prognosis and are often predicted to be non-responsive to the first administration of IVIG.
