Atypical Presentation of Intracardiac Floating Thrombi in Hypereosinophilic Syndrome Complicated With Stroke and Systemic Embolization: A Case Report

摘要

Hypereosinophilic syndrome (HES) describes a disorder characterized by persistent peripheral blood eosinophilia with evidence of multiple target organs damage caused by eosinophilia. HES most commonly involves the heart, and cardiac involvement typically presents in the form of endomyocarditis or myocarditis with apical mural thrombus formation. We present a case with atypical cardiac presentation with massive intracardiac fragile thrombi, causing peripheral emboli and strokes. HES can present as floating thrombi with thin attachment to the left ventricle, and clinicians should also be vigilant of thromboembolic complications and initiate early therapy to prevent or reduce the potential complications of HES.
