CT and MRI in the Evaluation of Thoracic Aortic Diseases
Figure 16
Contained rupture—(a) noncontrast CT scan in a patient presenting with acute chest pain shows nonspecific soft tissue adjacent to descending thoracic aorta. (b) Contrast enhanced CT at the same level shows lack of distinction between the posterior wall of the aorta and the adjacent vertebral body, the “draped aorta” sign (curved arrow), which is indicative of a contained rupture.
