Clinical Summary

A 58 years old man with Claudication and Iv drug user

Imaging Findings

CT scans shows a low-attenuation rounded structure arising from the right femoral artery

Differential Diagnosis

-------------------

Final Diagnosis

Femoral artery pseudoaneurysms

Discussion (Related Text)

Femoral artery pseudoaneurysms are usually iatrogenic as the femoral artery is the vessel of choice for most endovascular arterial interventions. Unenhanced CT scans may demonstrate a low-attenuation rounded structure arising from the donor artery. Intermediate or high attenuation (haemorrhage) adjacent to the pseudoaneurysm may been seen and indicates pseudoaneurysmal rupture, which may vary in attenuation dependant on being chronic or acute. The pseudoaneurysmal wall is usually smooth and well defined except in a mycotic pseudoaneurysm, where the wall can be thickened, irregular, or ill defined. CT angiographyMay demonstrate a contrast filled sac. However, the entire pseudoaneurysm however may not fill with contrast material. If a low-attenuation area remains within the pseudoaneurysm, it usually indicates partial thrombosis . A communication with a donor artery is adjacent to the pseudoaneurysm can usually be seen.
