RESUMEN
Myocarditis is an inflammatory disease of the myocardium secondary to infectious and noninfectious insults. The most feared consequence of myocarditis is sudden cardiac death owing to electrical instability and arrhythmia. Typical presenting symptoms include chest pain, dyspnea, palpitations and/or heart failure. Diagnosis is usually made with history, electrocardiogram, biomarkers, echocardiogram, and cardiac MRI (CMR). Application of the Lake Louise criteria to CMR results can help identify cases of myocarditis. Treatment is usually supportive with medical therapy, and patients are recommended to abstain from exercise for 3 to 6 months. Exercise restrictions may be lifted after normalization on follow-up testing.

Eosinophilic myocarditis is a rare form of myocarditis that may manifest from cancer-mediated inflammation. A case of eosinophilic myocarditis secondary to metastatic melanoma is described; metastatic melanoma can cause a T helper type 2 lymphocyte-mediated increase in circulating levels of interleukin-5, which is known to stimulate eosinophil proliferation resulting in myocardial inflammation and fibrosis. Cardiac imaging with transesophageal echocardiography revealed a large immobile left ventricular apical thrombus. Cardiac MRI was then performed and revealed enhancing fibrosis along the endocardial surface. © RSNA, 2019 Supplemental material is available for this article.
