Abstract
We report a case of hypereosinophilia causing multiple areas of cerebral infarcts. A 52-year-old Korean man presented with dysarthria and weakness in both arms. A brain MRI revealed multiple acute infarcts in the distal border zone with focal intracerebral hemorrhage, whereas a cerebral angiogram was not remarkable. The eosinophil count was 5,500/microL and was accompanied by elevated cardiac enzyme levels. The pattern of cerebral infarcts and laboratory results suggest a thromboembolic infarction associated with hypereosinophilia.
