Four patients who had low-back pain and sciatica were diagnosed as having a lumbar intraspinal extradural synovial cyst adjacent to a facet joint between the fourth and fifth lumbar vertebrae. The patients ranged in age from forty-nine to seventy-one years, and the symptoms and signs involved the fourth or fifth lumbar-nerve roots. Roentgenographically, degeneration of the intervertebral discs and facet joints was noted in every patient. Degenerative spondylolisthesis was also a frequent finding. Myelography and computed tomographic scans aided in diagnosis, revealing a soft-tissue lesion, occasionally rimmed with calcification, adjacent to the involved facet joint. The treatment was surgical excision of the cyst, as well as complete laminectomy if there was concomitant spinal stenosis. Follow-up, ranging from eighteen to twenty-five months, revealed complete resolution of the sciatica in all patients.
四名患有腰痛和坐骨神经痛的患者被诊断为在第四和第五腰椎之间的小关节附近存在腰椎椎管内硬膜外滑膜囊肿。患者年龄在49岁至71岁之间，症状和体征累及第四或第五腰神经根。X线检查发现，每位患者均存在椎间盘和小关节退变。退变性椎体滑脱也很常见。脊髓造影和计算机断层扫描有助于诊断，显示在受累小关节附近有一个软组织病变，偶尔有钙化边缘。治疗方法是手术切除囊肿，如果伴有椎管狭窄则进行全椎板切除术。随访时间为18至25个月，结果显示所有患者的坐骨神经痛均完全缓解。
