Shock: an unusual presentation of Kawasaki disease

Kawasaki disease (KD) is a common acute systemic vasculitis of childhood. Although KD has wide spectrum of clinical features, shock is not one of its common presentation form. We describe a 5-month-old female infant with severe shock syndrome requiring fluid resuscitation, inotropic support, and PICU admission. She was diagnosed retrospectively to have KD complicated by coronary artery aneurysms in spite of receiving early course of IV immunoglobulin. Conclusion: Diagnosis of KD could be missed in the pediatric intensive care unit because of its atypical presentation and the wide array of associated clinical symptoms. Subsequently, intensivists and emergency room physicians should maintain a high index of suspicion not to miss it or diagnose it at an advanced stage of the illness.
