Presentation
Presented to ER with twisted knee. Incidental finding on X-ray
Patient Data
There is an area of faint curvilinear calcification over the superior aspect of
the popliteal fossa on the lateral view measuring up to 23 mm AP diameter, not
seen previously. The appearance is suspicious for a popliteal artery aneurysm.
Ultrasound examination of the popliteal fossa confirms the presence of a
popliteal artery aneurysm with a maximum transverse diameter of 23 mm.
There is a 3.2 cm partially thrombosed aneurysm arising from the P2 segment
of the right popliteal artery. No additional aneurysms were identified.
Case Discussion
The popliteal artery aneurysm in this case exceeds 2 cm diameter and contains significant thrombus, therefore qualifying for treatment. Options include open repair vs endovascular covered stent insertion.
