Clinical History

Crush accident in a child

Differential Diagnosis List

Blunt aortic lesion at the level of the isthmus in a crushed child

Imaging Findings

16-year-old female child run over and crushed by a small truck

Discussion

Blunt aortic injuries are encountered in less than 0.5% of blunt chest trauma. They occur in high-speed traffic accidents and are thus associated with severe cranial, intrathoracic and intra-abdominal lesions. They usually lie at the aortic isthmus. Plain film patterns, notably mediastinal widening, may be difficult to interprete, due to thymic presence. As in adults, spiral computed tomography and trans-esophageal echography most often replace time-consuming and invasive aortography.
