Why the study?
Eosinophilic myocarditis is a cardiac manifestation of hypereosinophilic syndrome with high mortality that shares imaging features with other restrictive cardiopathies.

Non-invasive imaging with cardiac magnetic resonance is useful in narrowing the differential diagnosis to support the use of invasive endomyocardial biopsy for diagnosing eosinophilic myocarditis, even when absolute eosinophil counts are below the typical threshold.
Eosinophilic myocarditis (EM) is a cardiac manifestation of hypereosinophilic syndrome with a high mortality rate. EM shares imaging features similar to other restrictive cardiopathies, and include patchy intramural late gadolinium enhancement on cardiac magnetic resonance with or without presence of biventricular thrombus. Diagnosis is confirmed on histopathology, and is the current gold standard. Here we report clinical presentation and imaging findings of EM in a 70-year-old woman who presented with fever and chills.
