Summary

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.
