A case series of eosinophilic myocarditis: different faces of the same coin.

EM is an underdiagnosed and potentially life-threatening disease. Therefore, a high clinical suspicion for EM should arise when patients with signs and symptoms of cardiovascular disease develop hypereosinophilia or vice versa. Early identification of this condition using multimodality imaging and EMB is of paramount importance as the disease may progress to the irreversible late fibrotic stage if treatment is delayed.
