Intradural extramedullary epidermoid (EC) cysts are uncommon (0.2-1%). Acquired tumors appear more frequently as a late complication of lumbar punctures (40%). The authors present three cases of epidermoid cysts of the cauda equina which were surgically treated in their department during the past five years. All three had suffered lumbar punctures for rachianesthesia 6-9 years prior to their presentation. The patients' ages ranged between 19 and 31. Surgical treatment was deemed necessary because of the space-occupying nature of this slow-growing lesion, and this indication was supported by the MRI findings. Two-level laminectomy and microsurgical total tumor ablation were performed in all three cases. There were no postoperative complications.
硬脊膜内髓外表皮样囊肿（EC）较为罕见（0.2%-1%）。后天性肿瘤更常作为腰椎穿刺的晚期并发症出现（40%）。作者介绍了过去五年在其科室接受手术治疗的三例马尾神经表皮样囊肿病例。所有三例患者在出现症状前6至9年都曾接受过腰麻腰椎穿刺。患者年龄在19岁至31岁之间。由于这种生长缓慢的病变具有占位性，因此认为有必要进行手术治疗，MRI检查结果也支持了这一手术指征。所有三例均进行了两级椎板切除术和显微手术全肿瘤切除。术后无并发症。
