Twelve patients with symptoms and signs simulating lumbar disc disease were found to have intradural tumours in the lumbosacral area. Of the nine patients with a neurofibroma, two had previously had a laminectomy for an erroneous diagnosis of disc herniation and one had three separate tumours which were excised in two successive operations. One of the three patients with an ependymoma had a coccygectomy before the correct diagnosis was made. Only one patient who had an ependymoma showed radiographic abnormalities suggesting a neoplastic lesion, but eight of the ten cases in which the cerebrospinal fluid was analyzed had a protein content of 50 mg per 100 ml. Myelography provided the correct diagnosis in all cases. Excision of the tumour resulted in full clinical recovery except for one patient with an ependymoma.
12例有类似腰椎间盘疾病症状和体征的患者被发现腰骶部存在硬脊膜内肿瘤。9例患有神经纤维瘤的患者中，2例曾因误诊为椎间盘突出而行椎板切除术，1例有3个独立肿瘤，分两次连续手术切除。3例患有室管膜瘤的患者中，1例在做出正确诊断前接受了尾骨切除术。只有1例患有室管膜瘤的患者显示出提示肿瘤性病变的影像学异常，但在分析脑脊液的10例病例中，有8例蛋白质含量为每100毫升50毫克。脊髓造影在所有病例中都做出了正确诊断。除1例患有室管膜瘤的患者外，肿瘤切除后患者临床完全康复。
