硬膜内型腰椎间盘突出症:2例报告和综述△

Intradural lumbar disc herniation: 2-case report with literature review

摘要:

硬膜内椎间盘突出（intradural lumbar disc herniation, IDH） 是一种罕见疾病，其诊断易与椎管内肿瘤混淆。MRI 在临床诊断中发挥关键作用，有助于术前鉴别诊断。本文报道了2 例病例，均为男性，年龄分别为52、60 岁，涉及L4/5 节段。病例1 影像显示硬脊膜和纤维环破裂，而病例2 术前误诊为肿瘤，最终证实为IDH，2 例患者经手术治疗后恢复良好，无严重并发症。本文通过国内外文献回顾，讨论了IDH 的治疗策略，包括显微镜、微创技术发展及其在手术中的应用，旨在提升对IDH诊断和治疗的认识，为临床医生诊断治疗该疾病提供借鉴。

Abstract:

Intradural lumbar disc herniation (IDH) is a rare condition, and its diagnosis is often confused with intraspinal tumors. MRIplays a key role in clinical diagnosis and helps in preoperative differential diagnosis. We report two cases, both male, aged 52 and 60 years,involving L4/5 segments. The imaging of case 1 showed rupture of the dura and annulus fibrosa, while case 2 was misdiagnosed as a tumor be-fore surgery and eventually proved to be IDH. The two patients recovered well after surgical treatment without serious complications. Basedon the review of domestic and foreign literature, this paper discusses the treatment strategies of IDH, including the development of micro-scopes and minimally invasive techniques and their application in surgery, aiming to improve the understanding of diagnosis and treatmentof IDH, and provide references for clinicians to diagnose and treat this disease.
