We report a case of lumbosacral plexopathy caused by the rupture of a common iliac artery aneurysm. The patient presented with sciatic type symptoms of lower back pain radiating to his left leg with associated numbness and weakness in the L4-S1 distribution. He also had reduced anorectal tone. A CT scan showed a large haematoma in the left side of the pelvis from a ruptured 8 cm common iliac artery aneurysm. Sciatica is commonly due to a prolapsed intervertebral disc, although spinal canal stenosis, spondylolisthesis, piriformis syndrome and spinal tumours and other causes need to be considered. This case serves to increase the awareness of the possibility of another uncommon cause, especially when additional atypical neurological symptoms exist.
我们报告一例由髂总动脉瘤破裂引起的腰骶丛神经病。患者表现为坐骨神经型腰痛，放射至左腿，伴有 L4-S1 分布区的麻木和无力，肛门直肠张力降低。CT 扫描显示左侧骨盆有一个 8 厘米大的髂总动脉瘤破裂导致的血肿。坐骨神经痛通常是由于椎间盘脱垂引起的，尽管还需要考虑椎管狭窄、脊椎滑脱、梨状肌综合征和脊柱肿瘤等其他原因。本例旨在提高对另一种不常见病因的可能性的认识，特别是当存在其他非典型神经症状时。
