If a child has an abdominal aneurysm, doctors and nurses might notice it during a physical exam. With the advent of new noninvasive imaging methods, particularly state-of-the-art magnetic resonance (MR) imaging and multidetector computed tomography (CT) technology with increased z-axis coverage, higher spatial resolution (smaller detectors), and higher temporal resolution (faster 360° rotation times), evaluation of the aorta and its branches is possible with faster imaging times, fewer motion artifacts, and also less contrast material volume. Patients may also suffer thoracic aneurysms (in the chest cavity). ECG-gated CT ruled out aortic dissection and leak but there was progressive dilatation of the arch aneurysm up to 6 cm over a few months.

It is usually seen at the anteromedial aspect of the aorta at site of the aortic isthmus, where the ligamentum arteriosum attaches. Inherited thoracic aortopathies denote conditions in which abnormalities lead to thoracic aortic wall weakness or abnormal aortic hemodynamic profiles, predisposing patients to aortic dilatation, aneurysm formation, and acute aortic complications.

An aortic aneurysm is an enlargement of the aorta to greater than 1.5 times normal size. TAA occurs in 5-10/100 000 person-yr. 9 Up to 60% occur at the aortic root (ie, aortic root dilation) or in the ascending aorta, and the remainder in the descending thoracic aorta. A thoracic aortic aneurysm might show up when doctors do an ultrasound scan of the heart (called an echocardiogram). Vesalius is credited with the first description of a thoracic aortic aneurysm in 1543.
