    Abstract:
    Sciatica is defined as pain or discomfort along the regions innervated by the sciatic nerve. Compression or irritation of lumbar spinal roots, most commonly because of lumbar disc herniation or spinal stenosis, causes sciatica in the vast majority of cases. Although it is rather uncommon, many pathologies have reported to cause nondiscogenic sciatica. A 70-year-old woman presented with intractable sciatic pain which was not elicited by posture change or cough. Sitting on the affected side provoked more pain than standing or walking. Magnetic resonance imaging revealed both spondylolisthesis with lumbar stenosis and compression of the gluteal portion of the sciatic nerve by varicotic gluteal veins. Given the atypical presentation of spinal root compression, gluteal vascular compressive neuropathy was suspected. Ligation and resection of varicotic vein resulted in relief of the patient's pain. To our knowledge, cases with varicosity-caused sciatica were limited in the literature review.
