CTICasesMinimal traumatic intimal tear of the aorta
Imaging findings
CT angiogram following blunt trauma (20-foot fall) shows rib fractures and a small filling defect (<10 mm) at the aortic isthmus, representing an intimal tear, which resolved completely on follow-up imaging 48 hours later.
Key takeaways
Minimal aortic intimal tears (<10 mm) without mediastinal hematoma are a minor form of blunt traumatic aortic injury. They typically resolve spontaneously without surgical or endovascular intervention.
