Primary heart angiosarcoma detected by magnetic resonance imaging

We present a case of primary heart angiosarcoma in a 38-year-old male. The patient presented with severe dyspnoe and arrhythmia. Echocardiography showed multiple solid masses in the pericardium and pericardial effusion. Chest radiography revealed left-sided pleural effusion and suspicion of a mass projected on the right atrium. Non-enhanced chest computed tomography raised the suspicion of a pericardial neoplasm projected on the right atrium adjacent to ascending aorta with markedly thickened pericardium and multiple round-shaped masses around the heart. Cardiac-gated magnetic resonance imaging demonstrated an inhomogeneous mass in the free wall of the right atrium adjacent to ascending aorta and multiple pericardial masses. Biopsy performed through thoracoscopy confirmed the diagnosis of a primary heart angiosarcoma.
