椎间盘囊肿是罕见的病变，可导致难治性坐骨神经痛。由于它们非常罕见，它们的确切来源和临床表现的细节仍然未知。作者报告了五名治疗椎间盘囊肿的男性。手术时患者的平均年龄为32岁（范围25-38岁）。所有患者均出现下肢疼痛，直腿抬高试验结果均为阳性。3名患者报告运动无力，4名患者有感觉障碍——症状与腰椎间盘突出症患者相似。磁共振成像显示不同大小的球形硬膜外病变，分别在T1和t2加权图像上呈现低信号和高信号强度。椎间盘造影显示囊肿与椎间盘之间有明显的联系，所有患者均伴有重复性腿痛。所有患者均行后路减压和囊肿切除，并伴有或不伴有椎间盘切除术。所有患者术后神经根症状均有明显改善，随访期间无复发性病变。
Discal cysts are rare lesions that can result in refractory sciatica. Because they are so rare, their exact origin and details of the clinical manifestations are still unknown. The authors report on five men treated for discal cysts. The mean age of the patients at the time of the surgery was 32 years (range 25-38 years). All patients suffered from lower-extremity pain and the results of the straight leg-raising test were positive in all cases. Three patients reported motor weakness and four had sensory disturbance-symptoms similar to those found in patients with lumbar disc herniation. Magnetic resonance imaging demonstrated spherically shaped extradural lesions of various sizes with low and high signal intensities on T1- and T2-weighted images, respectively. Discography revealed obvious communication between the cyst and the intervertebral disc with reproducible leg pain in all patients. All patients underwent posterior decompression and excision of the cysts either with or without additional discectomy. The radicular symptoms were remarkably improved in all patients immediately after surgery, and no recurrent lesions were noted during follow up.
