Unraveling the Mystery of Young Stroke: A Rare Cardiac Manifestation of Systemic Disease

A 38-year-old male presented with a history of acute-onset hemiparesis 6 months back. On evaluation, he was found to have eosinophilia. Echocardiography was done which revealed a thrombus in the left atrium attached to the posterior mitral leaflet. The rest of the cardiac chambers were normal. Diagnosis of idiopathic hypereosinophilic syndrome was made after extensive evaluation. The patient was started on steroids and oral anticoagulation, following which eosinophil count and size of thrombus reduced.
