A case of idiopathic hypereosinophilic syndrome manifested as regional wall motion abnormalities in echocardiogram and pericardial effusion / 대한내과학회지

ABSTRACT

Idiopathic hypereosinophilic syndrome is characterized by unexplained blood eosinophilia > 1500/mm3 for more than 6 months and eosinophilic infiltration of several organs. A major source of the morbidity and mortality of this syndrome is the associated cardiac involvement. The typical cardiac involvement includes endocardial fibrosis and mural thrombus. We report a case of idiopathic hypereosinophilic syndrome manifested as multiple regional wall motion abnormalities and moderate pericardial effusion on transthoracic echocardiography that was successfully treated by pericardiostomy and steroid therapy.
