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.
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0.35/10万。值得注意的是，尽管20%累及中枢神经系统，但发生在脊柱的仅占十分之一，而发生在脑部的占十分之九。
病例描述
一名46岁女性出现18个月的左下肢坐骨神经痛。检查时，她直腿抬高受限60°，但其他神经系统检查正常。腰椎磁共振成像显示L4-L5水平有一个哑铃形肿瘤占据椎管，导致马尾神经受压，并延伸至左侧L45椎间孔。患者成功接受了L4左侧半椎板切除术以切除肿瘤。术后世界卫生组织（WHO）组织病理学检查结果与SFT/WHO I级血管外皮细胞瘤（HPC）一致。
结论
一名46岁女性患有腰椎L4 SFT并延伸至左侧L45椎间孔，成功接受了左侧半椎板切除术，以实现SFT/WHO I级HPC的根治性肿瘤切除（GTR）。
