Overview

Case report reveals buttock claudication misdiagnosed as lumbar spinal stenosis, suggesting improved diagnostic approaches.

Key Points

  • The aim is to highlight the misdiagnosis of vascular claudication as neurogenic claudication in an older patient.
  • Case report of a 71-year-old male presenting with left buttock pain.
  • Initial misdiagnosis based on MRI of lumbar spinal stenosis.
  • Use of diagnostic transforaminal epidural steroid injections and endoscopic decompression.
  • Ankle-brachial index testing and computed tomography angiography for vascular evaluation.
  • Initial treatments did not alleviate symptoms.
  • Ankle-brachial index revealed significant vascular impairment (0.71).
  • Computed tomography angiography showed total occlusion of the left common iliac artery.
  • Percutaneous transluminal angioplasty with stenting resolved the patient's symptoms.
