Characterization of an unusual right atrial mass by echocardiography, magnetic resonance imaging, computed tomography, and angiography

A right atrial mass was discovered by echocardiography in a 53-year-old man . A work-up consisting of magnetic resonance imaging and computed tomograph y studies established the diagnosis of atrial lipoma. The echocardiographic features are compared with the radiological findings, and the characterist ics permitting differentiation of lipoma front other causes of cardiac mass es are discussed. in this case, echocardiography not only permitted the ini tial identification of the mass but also proved to be useful in follow-up o f its evolution over time, thereby influencing the therapeutic management.
