Abstract

Background: Solitary fibrous tumors (SFTs) account for 3.7% of all soft-tissue sarcomas, with an annual incidence of 0.35/100,000 individuals. Notably, although 20% involve the central nervous system, only one in 10 occurs in the spine versus the brain.

Case description: A 46-year-old female presented with 18 months of left lower extremity sciatica. On examination, she had a 60° limitation of straight leg raising but was otherwise neurologically intact. The lumbar magnetic resonance revealed a dumbbell tumor at the L4-L5 level filing the canal, causing cauda equina compression and extending into the left L45 foramen. The patient successfully underwent a L4 left hemi-laminectomy for tumor resection. The postoperative World Health Organization (WHO) histopathology was consistent with a SFT/WHO Grade I hemangiopericytoma (HPC).

Conclusion: A 46-year-old female with a lumbar L4 SFT with the left L45 foraminal extension successfully underwent a left hemilaminectomy for GTR of an SFT/WHO Grade I HPC.

一例腰椎单发纤维瘤或血管瘤。

背景：孤立性纤维瘤（SFTs）占所有软组织肉瘤的3.7%，年发病率为0.35/100,000人。值得注意的是，虽然有 20% 的肿瘤涉及中枢神经系统，但每 10 例中只有 1 例发生在脊柱而非大脑：一名 46 岁的女性因左下肢坐骨神经痛就诊 18 个月。经检查，她的直腿抬高受限 60°，但其他神经系统正常。腰椎磁共振检查显示，L4-L5水平的哑铃状肿瘤堵塞了椎管，导致马尾受压，并延伸至左侧L45孔。患者成功接受了左侧 L4 半椎板切除术，切除了肿瘤。术后世界卫生组织（WHO）组织病理学检查结果与 SFT/WHO I 级血管细胞瘤（HPC）一致：结论：一名 46 岁女性腰椎 L4 SFT 左侧 L45 椎孔扩展患者成功接受了左侧半椎板切除术，以切除 SFT/WHO I 级 HPC。
