Ascending Aorta

Ascending Aortic Aneurysm

This series of images are from a CTscan showing an ascending aortic thoracic aneurysm. There is evidence of heavy calcification of the aortic valve (aortic sclerosis), an aneurysm confined to the ascending aorta (b,c,d), and tortuosity of the descending aorta (d). The cause for the aneurysm is probably a combination of systemic hypertension, aortic stenosis and atherosclerotic degeneration of the wall.

Contrast CT Masks Thrombosed Dissection

Unenhanced Reveals Small Hyperdense Dissection

This series of CT scans were taken 1 day apart. The patient presented with chest pain and the soft tissue changes around contrast filled aorta (a,b,c) suggested a chronic dissection, or an acute thrombosed dissection. 1 day later the non-contrast CT clearly reveals an acute thrombosed dissection (d,e,f) that started in the arch and extended along the descending thoracic aorta. The last series (g,h,i) enhance the non contrats study. A non contrast CT followed by contrast injection, is an important tchnique to optimally characterise acute changes in this clincal setting.

Expanding Aneurysm of the Arch

This combination CXR and CT reveals an expanding aneurysm of the arch fromm 2002 to 3003. The CT shows three aneurysm in the arch of the aorta. The largest seen in image 3,6, and 7 accounts for the finding in the left apex of the CXR, while a second pseudoaneurysm is seen on the lateral border of the knob (4,8) and a penetrating ulcer medially (5) 32029c

Descending Aorta


This series of CTscans with contrast show a distal thoracic aortic aneurysm showing thrombus in the lumen (a,b) and irregular atherosclerotic plaque. The presence of calcified wall extrinsic to the thrombus makes a fusiform aneurysm likely, and focal thrombosed dissection secondary to ulcer penetration less likely.

Traumatic Dissection of the Abdominal Aorta wit Loss of Perfusion of the Left Renal Artery

These images represent a traumatic dissection of the abdominal aorta caused by a compression injury to the abdomen. The angiograms in a and b shows what appears to be a complex tear of the aorta with a dissection and then a subtotal obstruction of the aorta distally. The CTscan shows (c) the dissection to better effect, with a subtotal narrowing of the aorta distally. Note also the injury of the left renal artery on the angiogram as well as the lack of perfusion of the left kidney on the CT scan.

Scalloping of Vertebra and Mycotic Aneurysm

This combination of images from a CTscan of the abdomen are of a middle aged man who presented with back pain and fever, with a remote history of AAA repair. The lateral scout film shows scalloping of vertebral bodies 2 and 3 (a) highighted in green overlay in b. The CTscan with soft tissue windows (c) and bone windows (d) show a complex fluid collection surrounding the aorta which proved to be a perigraft infection.
