Key result
Early CMR enables non-invasive diagnosis of acute eosinophilic myopericarditis, guiding prompt steroids and rapid recovery.
Why the study?
Early non-invasive diagnosis of acute eosinophilic myopericarditis (AEM) before cardiac biopsy is important but not well established.
Does cardiovascular magnetic resonance enable early non-invasive diagnosis of acute eosinophilic myopericarditis?

Does cardiovascular magnetic resonance enable early non-invasive diagnosis of acute eosinophilic myopericarditis?
CMR enables early non-invasive diagnosis and visualization of acute eosinophilic myopericarditis, allowing for prompt initiation of steroid therapy before biopsy confirmation.
May support early CMR in suspected cases; hypothesis-generating and requires prospective validation before practice change.
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.

Kim et al. (2011) conducted a case report in Acute Eosinophilic Myopericarditis (n=1). Cardiac Magnetic Resonance and Steroid therapy was evaluated on Clinical and imaging improvement. Early use of cardiac magnetic resonance enabled the non-invasive diagnosis of acute eosinophilic myopericarditis, leading to prompt steroid therapy and rapid clinical improvement.
