Abstract

Dorsal epidural disc migration (DEDM) is a rare and atypical presentation of lumbar disc herniation characterized by the migration of a disc fragment into the dorsal epidural space. This unusual migration pattern presents unique diagnostic challenges, as it can mimic other serious spinal pathologies such as epidural abscesses, hematomas, and synovial cysts. Magnetic resonance imaging (MRI) remains the gold standard for accurately diagnosing DEDM and differentiating it from other pathologies. Surgical intervention, particularly microdiscectomy, has shown favorable outcomes in resolving symptoms associated with nerve compression and minimizing recurrence rates. This report presents a case of DEDM in a 39-year-old male with persistent sciatica, analyzing MRI characteristics and surgical treatment.

背侧硬膜外椎间盘移位- mri特征和手术显微椎间盘切除术治疗：病例报告和文献复习

背侧硬膜外椎间盘移位（DEDM）是一种罕见的非典型腰椎间盘突出症，其特征是椎间盘碎片移位到背侧硬膜外间隙。这种不寻常的迁移模式提出了独特的诊断挑战，因为它可以模仿其他严重的脊柱病变，如硬膜外脓肿、血肿和滑膜囊肿。磁共振成像（MRI）仍然是准确诊断DEDM并将其与其他病理区分开来的金标准。手术干预，特别是微椎间盘切除术，在缓解神经压迫相关症状和减少复发率方面显示出良好的结果。本文报告一例39岁男性持续性坐骨神经痛DEDM，分析MRI特征和手术治疗。
