CTICasesIatrogenic aortofemoral bypass graft mimicking mediastinal pathology
Imaging findings
Chest radiograph and CT show a double-barrel aortic contour in the posterior mediastinum, corresponding to an aorta-to-femoral bypass graft. The native infrarenal aorta was chronically occluded.
Key takeaways
Aortofemoral bypass grafts originating from the thoracic aorta can project as a retrocardiac mass on chest radiographs. Cross-sectional CT imaging easily confirms the bypass graft and its patency.
