Multimodality imaging of biatrial myxomas in an asymptomatic patient

Myxomas are located in the left atrium in 75-80% of cases and almost always present with signs and symptoms of a thromboembolic event. Biatrial myxomas are rare, and their incidence is generally less than 2.5% of all myxomas. We herein present a case of biatrial myxomas as an incidental finding by echocardiography where the patient underwent surgery. Echocardiography continues to be the initial imaging modality for intracardiac masses. Cardiac magnetic resonance provides superior tissue characterization, particularly important in differentiating a myxoma from a thrombus. Appropriate use of these non-invasive imaging modalities may lead to a correct diagnosis and good outcome. <Learning objective: In this report we present a rare case of cardiac biatrial myxomas. Multimodality imaging, especially delayed enhancement cardiac magnetic resonance imaging, provided specific findings for the diagnosis.>.
