Giant Thoracic Aortic Aneurysm Rupture in a Patient with Extensive Atherosclerotic Disease.

Aneurysmal dilatations can affect any aortic segment and represent the result of various causes, atherosclerotic disease being the most common and frequently involved. We hereby illustrate a case of a patient with thoracic aortic aneurysm rupture due to extensive atherosclerotic disease, with multiple complex penetrating ulcerated atherosclerotic plaques located in the descending aorta. CT angiography evaluation included a comprehensive description of imaging features and extent of the thoracic aortic aneurysm, the presence of thrombus, relationship to adjacent structures and branches, associated complications. Teaching Point: Thoracic aortic aneurysm rupture due to extensive atherosclerotic disease with multiple penetrating ulcers.
