Radiography chest shows a common finding observed in elderly patients - atherosclerotic senile ectasia of the thoracic aorta. In this case, is causing compressive mass effect on the left recurrent laryngeal nerve and consequent paralysis of the vocal cord.  This is termed Ortner or cardiovocal syndrome.

The term aneurysm is used when axial diameter of the thoracic aorta is >5 cm and when it measures 4-5 cm the term dilatation is used ¹.

Asymptomatic aneurysmal dilatation <6.5 cm is treated conservatively and monitored every 6-12 months. The choice of imaging techniques for evaluation of this pathology is CT and MRI with contrast. If the aneurysm is >6.5 cm, has annual growth >1 cm, or is symptomatic, intervention is considered because of the risk of rupture. In general, when possible, endovascular repair is the treatment of choice, with reduced morbidity and mortality ².
