CT Angiogram Thoracic Aorta:
Arterial phase contrast enhanced scans were performed (Omnipaque 350). No previous cross-sectional imaging for comparison.
Findings:
No traumatic aortic injury or mediastinal haematoma. Note is made of a patent ductus arteriosus. The right heart and pulmonary arteries not dilated. Remnant thymic tissue noted. No enlarged hilar, mediastinal or axillary lymph nodes.
The lungs are clear with no consolidation, collapse, pulmonary nodules or masses. No pneumothorax or pleural effusions.
Multiple locules of gas and associated stranding/haematoma are in keeping with a soft tissue injury anterior to the midshaft of the left clavicle. No underlying fracture of the imaged clavicle.
No thoracic spine, rib or sternal fracture.
Conclusion:
1. No traumatic aortic injury. Narrow calibre patent ductus arteriosus without evidence of pulmonary arterial hypertension or RV hypertrophy. Cardiology review suggested.
2. Gas within the soft tissues anterior to the midshaft of the left clavicle is highly suspicious for a soft tissue laceration. No left clavicular fracture, however the clavicle has been incompletely imaged.
