Figure 10

Acute  traumatic  aneurysm—postcontrast axial CT scan image in a 28-year-old male who was involved in a motor vehicle accident shows a small focal outpouching from the anterior aspect of the proximal descending thoracic aorta (curved arrow), which is indicative of aortic trauma. Note the absence of mediastinal hematoma in this patient.
