Kawasaki disease (KD) is an acute febrile illness that is characterized by systemic inflammation usually involving medium-sized arteries and multiple organs during the acute febrile phase, leading to associated clinical findings. The diagnosis is based on the principal clinical findings including fever, extremity changes, rash, conjunctivitis, oral changes, and cervical lymphadenopathy. However, KD diagnosis is sometimes overlooked or delayed because other systemic organ manifestations may predominate in acute phase of KD. As a cardiovascular manifestation, an acute pericarditis usually shows a small pericardial effusion, but large pericardial effusion showing clinical signs of cardiac tamponade is very rare. Here, we described a case of incomplete KD presenting with impending cardiac tamponade, and recurrent fever and pleural effusion.
