How are thoracic aortic aneurysms diagnosed?

Thoracic aortic aneurysms can be hard to diagnose because they usually develop slowly and do not cause many symptoms. Unless the aneurysm has ruptured, a physical exam with a doctor likely will be normal.

Undergoing imaging tests for other symptoms or conditions is often how thoracic aortic aneurysms are detected. These tests can include a chest x-ray, echocardiogram (ultrasound of the heart and part of the aorta), or a computed tomography (CT) scan. A CT scan will show the size of the aorta and the exact location of the aneurysm.

An aortogram or angiogram (a special set of x-ray images made when dye injected into the aorta) may also be performed, which can help identify the aneurysm and any branches of the aorta that may be involved.
