  		Fig. 1A. —53-year-old man injured in motor vehicle collision. Right anterior oblique aortogram was prospectively interpreted as showing contour abnormality in root of aberrant right subclavian artery consistent with traumatic pseudoaneurysm (arrow).

  		Fig. 1B. —53-year-old man injured in motor vehicle collision. Contrast-enhanced CT scan reveals aberrant right subclavian artery, coursing behind trachea and esophagus (short arrow). Note small diverticulum of Kommerell (long arrow) and lack of periaortic hematoma, intimal injury, or pseudoaneurysm. Patient was treated conservatively without sequela.

  		Fig. 2A. —80-year-old man injured in motor vehicle collision. Contrast-enhanced CT scan reveals triangular contour abnormality along lateral aspect of aortic arch (arrow), which persisted on delayed images (not shown). No adjacent paraaortic hematoma and no obvious atherosclerotic plaque are seen at this level or elsewhere.

  		Fig. 2B. —80-year-old man injured in motor vehicle collision. Right posterior oblique aortogram appears unusual but was interpreted as negative for acute injury. Clinically, patient was thought to have potential occult vascular injury. However, because of advanced age, he was treated conservatively without sequela.

  		Fig. 3A. —52-year-old man injured in motor vehicle collision. Contrast-enhanced CT scan reveals slight effacement of proximal descending thoracic aorta at 9- to 12-o'clock position by minimal adjacent periaortic hematoma (arrow).

  		Fig. 3B. —52-year-old man injured in motor vehicle collision. Contrast-enhanced CT scan obtained 3 mm more cephalad than A reveals subtle intimal flap versus possible plaque involving proximal descending thoracic aorta (arrow). Scan was prospectively interpreted as being inconclusive but suggestive of injury.

  		Fig. 3C. —52-year-old man injured in motor vehicle collision. Left anterior oblique aortogram reveals subtle linear defect and contour anomaly in same region of proximal descending thoracic aorta consistent with traumatic intimal flap (arrows). Injury was confirmed surgically and subsequently repaired.
