Abstract:
An unusually large, noncalcified popliteal artery aneurysm causing cortical erosion was erroneously diagnosed as a soft-tissue sarcoma. The case stresses the importance of excluding a vascular cause of a mass whenever biopsy is considered. We review the clinical and radiological features of popliteal artery aneurysm and describe the appearance of the aneurysm on MR.
Insights
A large popliteal artery aneurysm was misdiagnosed as sarcoma, highlighting the need to consider vascular causes before biopsy. Magnetic resonance imaging (MRI) aids in identifying these aneurysms.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Radiology
Background:
- Popliteal artery aneurysms (PAAs) are uncommon but can lead to serious complications.
- Misdiagnosis of PAAs can delay appropriate treatment and lead to unnecessary procedures.
Observation:
- A case of a large, noncalcified popliteal artery aneurysm causing cortical erosion is presented.
- The aneurysm was initially misdiagnosed as a soft-tissue sarcoma.
Findings:
- The study reviews the clinical and radiological features of popliteal artery aneurysms.
- Magnetic resonance (MR) imaging appearance of PAAs is described.
Implications:
- Emphasizes the critical importance of excluding vascular abnormalities before considering biopsy for a suspected soft-tissue mass.
- Highlights the role of advanced imaging like MRI in accurate PAA diagnosis.
- Underscores the need for increased awareness among clinicians regarding PAAs as a differential diagnosis for leg masses.
