large mobile aortic arch mass

Mobile luminal mass of aortic arch is an unusual finding in patients with peripheral embolization. To search the source of these emboli, aortic arch mass should be considered. To our knowledge, transesophageal echocardiography [TEE] can be a useful modality to demonstrate the nature and exact location of the mass. This report is illustrative of a large mobile aortic arch mass, histologically thrombus, found by TEE in a 48- year-old woman with embolic symptoms
