【 摘 要 】

A 14-year-old dog weighing 4 kg presented with hypotension only in the right forelimb.Thoracic radiography revealed a round soft tissue opacity near the aortic arch and belowthe second thoracic vertebra on a lateral view. Three-dimensional computed tomographyangiography clearly revealed stenosis and aneurysmal dilation of an aberrant rightsubclavian artery. Stenosis and aneurysm of an aberrant subclavian artery should beincluded as a differential diagnosis in dogs showing a round soft tissue opacity near theaortic arch and below the thoracic vertebra on the lateral thoracic radiograph.
