A rare persistent sciatic artery aneurysm caused buttock pain. Early diagnosis is challenging but crucial, especially in older adults with atherosclerosis, with sagittal MRI proving beneficial.

Area of Science:

  • Vascular Surgery
  • Radiology
  • Embryology

Background:

  • Persistent sciatic artery is a rare embryonic remnant.
  • Aneurysms in this artery are exceptionally uncommon.
  • Sciatic artery aneurysms can present with buttock pain.

Observation:

  • A case of buttock pain was attributed to a persistent sciatic artery aneurysm.
  • Preoperative diagnosis of this condition is often difficult.
  • The patient was an elderly individual with significant atherosclerotic changes.

Findings:

  • Sagittal magnetic resonance imaging (MRI) was instrumental in diagnosing the aneurysm.
  • Awareness of this rare abnormality is key for accurate diagnosis.
  • Atherosclerotic changes in elderly patients may predispose to this condition.

Implications:

  • Highlights the importance of considering rare vascular anomalies in clinical practice.
  • Emphasizes the diagnostic utility of MRI in complex vascular cases.
  • Suggests a potential link between atherosclerosis and persistent sciatic artery aneurysms in the elderly.
