本文报告6例黄韧带囊肿并腰神经根受压。所有患者都表现出反复的背痛和坐骨神经痛。检查包括计算机断层扫描、脊髓造影术，或两者兼而有之。只有一半的患者在手术前得到了正确的诊断。最后四位患者进行高分辨率计算机断层扫描，勾勒出中心低密度的囊性病变。所有患者均行手术切除。镜下可见黄韧带上长出致密的纤维状囊肿。管腔内有粘液样物质或坏死物，但没有上皮衬里。在坐骨神经痛病因的鉴别诊断中，必须考虑黄韧带囊肿。目前，确定的放射诊断可能仍然需要脊髓造影术和高分辨率计算机断层扫描相结合。讨论了与脊椎滑膜或神经节囊肿的鉴别。
Six cases of cyst of the ligamentum flavum with compression of a lumbar nerve root are reported. All patients exhibited recurrent back pain and sciatica. Investigation included computed tomography, myelography, or both. The correct diagnosis was reached before operation in only half the patients. High-resolution computed tomography performed in the four last patients outlined the cystic lesion with its low-density center. Surgical excision was performed in all patients. Microscopic examination showed a dense fibrous cyst arising from the ligamentum flavum. The lumen contained myxoid or necrotic material, but no epithelial lining. Cysts of the ligamentum flavum must be considered in the differential diagnosis of causes of sciatica. A firm radiological diagnosis may, at present, still require myelography combined with high-resolution computed tomography. Differentiation from synovial or ganglion cysts of the spine is discussed.
