Eosinophilic Myocarditis With Cerebral Infarction

Cerebral infarction in patients with eosinophilic myocarditis (EM) is a rare but serious complication. Although the major cause is the presence of intraventricular thrombus, the details remain unexplored. We illustrate a case of EM complicated by cerebral infarction, and we ascertained the cause through histologic findings in a cerebral thrombus. Careful follow-up should be considered, to monitor for the presence of intraventricular thrombus.
