Findings
Chest radiograph
- Widening of the superior mediastinum
- Hazy opacification of the left hemithorax, which may relate to airspace opacification and/or layering pleural fluid
CT
Chest
- Complex acute aortic injury just distal to the origin of the left subclavian artery with external contour irregularity and large surrounding mediastinal hematoma
- Additional site of acute aortic injury just below the diaphragmatic hiatus with distal extension into and occlusion versus near occlusion of the left renal artery. No large surrounding hematoma at this location
- Mediastinal hematoma displaces and mildly narrows the trachea, inferiorly displaces the left mainstem bronchus, and extends around the esophagus in the posterior mediastinum
- Moderate-sized left hemothorax
- Small right pleural effusion
- Dependent groundglass opacities in both lungs
Abdomen/Pelvis
- Decreased enhancement of the interpolar region and lower pole of the left kidney
- Heterogeneous enhancement of the right kidney
- Mild fat stranding adjacent to the left common iliac vein
- Flattened appearance of the IVC
- Focal fatty infiltration in the liver adjacent to the falciform ligament
- Cholecystectomy changes with mild intrahepatic and extrahepatic biliary duct dilation
- Small volume free fluid layering in the anatomic pelvis
- Hysterectomy
MSK
- Acute nondisplaced fracture of the left L1 transverse process
Diagnosis
Acute traumatic aortic injury
Sample Report
Severe acute traumatic aortic injury just distal to the origin of the left subclavian artery with external contour irregularity concerning for full-thickness mural tear. Limited evaluation for active bleeding as no delayed images were obtained through the chest, but there is a large surrounding mediastinal hematoma and moderate-sized left hemothorax.
Additional site of aortic injury just below the diaphragmatic hiatus with extension into and occlusion versus near occlusion of the left renal artery. No large surrounding hematoma. Resultant ischemia of the majority of the left kidney. Heterogeneous enhancement of the right kidney is likely the result of platelet aggregation in the setting of traumatic aortic injury.
Probable injury of the left common iliac vein.
Flattening of the IVC concerning for hypovolemia.
Acute nondisplaced left L1 transverse process fracture.
