Chest AP

Diagnosis With Brief Discussion

Diagnosis
traumatic rupture of descending aorta
Radiologic Findings
Brief Review
In this case, chest radiograph shows superior mediastinal widening, haziness of the left hemithorax suggesting hemothorax, slight deviation of trachea to right side (not well-seen in this screen). CT scan with intravenous contrast taken one day later reveals diffuse increased attenuation in mediastinal fat suggesting resolving hematoma or hemorrhage, and contour deformity and abrupt change of diameter of descending thoracic aorta on consecutive two CT images. This is traumatic injury of thoracic aorta.
Aortography shows aortic transection and pseudoaneurysm formation.
