title: Early non-invasive diagnosis and treatment of acute eosinophilic myopericarditis by cardiac magnetic resonance.
abstract: We report a case of early non-invasive diagnosis of acute eosinophilic myopericarditis (AEM) by cardiovascular magnetic resonance (CMR) before cardiac biopsy. A 35-yr-old woman presented with a flu-like illness, followed by pleuritic chest pain and shortness of breath. Transthoracic echocardiography revealed mild left ventricular (LV) systolic dysfunction with borderline LV wall thickness and moderate pericardial effusion. The patient had peripheral eosinophilia and CMR was performed immediately at first day of visit before cardiac biopsy. CMR showed diffuse subepicardial high T2 signals and diffuse late gadolinium enhancement in LV. Steroid therapy was immediately initiated and patient's symptom was rapidly improved. Endomyocardial biopsy at hospital day 3 reported multifocal mild infiltration of eosinophils and lymphocytes. The patient was finally confirmed as acute eosinophilic myopericarditis. This presentation emphasizes on the role of CMR which enables early non-invasive diagnosis of AEM and visualize the extent of the myocarditis.
