Hypereosinophilic syndrome (HES) is a diverse group of rare disorders, defined by persistent peripheral blood eosinophilia (>1500 per mm3), the absence of a primary cause of eosinophilia (such as parasitic or allergic disease), and evidence of eosinophil-mediated end-organ damage. Arterial aneurysms have been previously reported in these patients. This is the first report of a patient with HES and multiple venous aneurysms, causing recurrent pulmonary thromboembolism. Venous aneurysms can represent eosinophil-mediated, potentially fatal end-organ damage in patients with HES.
