Abstract

We describe 4 patients with stroke caused by hypereosinophilic syndrome, all of whom presented with border zone infarcts, and discuss the possible underlying mechanism. Cardioembolism (endomiocardial fibrosis) would coexist with impaired washout (perfusion disturbance due to high eosinophil count and/or eosinophil-derived substances), explaining the watershed characteristics of the infarcts.
