Symptomatic thoracic aorta mural thrombus.

Cases of mural aortic arch thromboses are generally associated with diffuse atherosclerosis of the aortic arch and have primarily been detected in elderly patients. However, the presence of mural thrombi in the aortic arch in young patients without diffuse atherosclerosis has rarely been reported. We describe a case of a hypercoagulable young patient with arterial embolism in whom investigations revealed a mural pedunculated aortic arch thrombosis without clear diffuse atherosclerotic lesions.
