CTICasesSternal Fracture with Retrosternal and Crus Hematomas
Imaging findings
CT chest in a trauma patient shows a sternal fracture with retrosternal hematoma, along with disruption of the anterior costal cartilages. Delayed contrast CT reveals a right diaphragmatic crus hematoma demonstrating active arterial contrast extravasation.
Key takeaways
In blunt chest trauma, sternal fractures can be associated with retrosternal and retroperitoneal hematomas. Active bleeding within the diaphragmatic crura can occur and should be searched for systematically on contrast-enhanced CT, as it can mimic mesenteric or solid organ injury.
