Abstract

Background: A patient presented with lumbago/sciatica attributed to a magnetic resonance (MR)-documented hugely dilated, partially calcified, and extrinsically compressive epidural varicose vein (EVV).

Case description: A 36-year-old male presented with 2 months of lumbago-sciatica; the only finding was a positive left-sided straight leg sign to 50°. The MR imaging demonstrated a hugely dilated, branching pattern flow void that caused marked displacement/compression of thecal sac and left S1 nerve root. The X-rays and computed tomography (CT) studies additionally showed a linear "string of beads" pattern of calcification at the L5/S1 level. Intraoperatively, an encapsulated, hugely dilated, compressive epidural vein was encountered; partial vein coagulation and gross total removal decompressed the neural elements. He recovered normal neurological function within 1 post-operative month.

Conclusion: A 36-year-old male presented with left-sided sciatica attributed to an MR and CT documented hugely dilated, partially calcified L5/S1 EVV. Once the EVV was coagulated and removed, the patient's symptoms resolved.

巨大扩张/部分钙化硬膜外静脉曲张引起椎内神经压迫/坐骨神经痛。

背景：患者表现为腰痛/坐骨神经痛，磁共振(MR)-证实巨大扩张，部分钙化，硬膜外静脉曲张（EVV）外源性压缩。病例描述：36岁男性，腰坐骨神经痛2个月；唯一的发现是左侧伸直的腿指向50°。磁共振成像显示一个巨大的扩张，分支型血流空洞，导致脊髓膜囊和左侧S1神经根明显移位/压迫。x射线和计算机断层扫描（CT）研究也显示在L5/S1水平呈线性“串珠状”钙化。术中，遇到一个包裹，巨大扩张，压缩硬膜外静脉；部分静脉凝血和大体全切除使神经元件减压。术后1个月内神经功能恢复正常。结论：一名36岁男性表现为左侧坐骨神经痛，MR和CT显示L5/S1 EVV巨大扩张，部分钙化。一旦EVV凝固并被移除，病人的症状就消失了。
