Recurrent infective endocarditis as a manifestation of Loeffler's endocarditis: The diagnostic importance of cardiac magnetic resonance imaging

The presence of infective endocarditis and simultaneous Loeffler's endocarditis has been reported once before by Menz et al. in 1994 published in Hertz. This case emphasizes the role of CMR as a diagnostic modality for Loeffler's endocarditis. Our patient had no peripheral hypereosinophilia. Myocardial biopsy conveys an increased risk for thromboembolic events and the possibility of a false negative result. CMR however, raised the suspicion of Loeffler's endocarditis, a diagnosis that was subsequently confirmed by bone marrow biopsy. The patient was treated with acenocoumarol and oral prednisone, which was gradually tapered after addition of mycophenolate mofetil.
