脊髓室管膜瘤是一种常见类型的原发性脊髓肿瘤，经常发生在腰椎。作者报告了两名患者，他们在终丝室管膜瘤出血后出现急性神经功能下降。由于诊断不确定性和对可能的硬膜内血管异常的担忧，两例患者均被转移到作者所在的机构。两例患者均接受了腰椎椎板切除术以切除肿瘤。病理结果均为黏液乳头状室管膜瘤。两例患者均显著恢复，随访时可走动并保持控制。这些病例说明了马尾出血性室管膜瘤引起的急性神经功能下降的罕见但具有临床意义的发病率，包括延迟诊断和治疗的可能性。
Spinal ependymomas are a common type of primary spinal cord neoplasm that frequently occurs in the lumbar spine The authors report on two patients who presented with acute neurological decline after hemorrhage into ependymomas of the filum terminale. Both were transferred to the authors' institution because of diagnostic uncertainty and a concern about possible intradural vascular abnormalities. Both patients underwent lumbar laminectomies for tumor resection. The pathological finding in each case was myxopapillary ependymoma. Both patients made a significant recovery and were ambulatory and continent at follow-up review. These cases illustrate the rare but clinically significant incidence of acute neurological decline caused by hemorrhagic cauda equina ependymomas, including the potential for delayed diagnosis and treatment.
