Imaging findings
Amorphous filling defects within the aorta on venous-phase CT, which appear more discrete on arterial-phase imaging, indicating a mobile mass.
Key takeaways
If "contrast mixing" artifact appears unusual or persists across phases, consider a mobile aortic thrombus. Follow-up imaging is essential to confirm the diagnosis.
