研究设计.一份病例报告。目的。目的：了解一例罕见的进行性黄韧带血肿。背景资料摘要。黄韧带血肿的文献报道仅2例。患者因黄韧带血肿导致进行性L5神经根病接受手术治疗。报告其临床及神经影像学特征，并复习文献。除了轻微的背部损伤外，无法确定该病例的病因。尽管保守治疗，症状进行了7个月。磁振造影显示L4-L5的硬膜外肿块病变与黄韧带相连。肿块在T1加权像上呈低信号，在T2加权像上呈中心高信号，边缘低信号。Gd-DTPA增强后边缘明显增强。切除肿块后，患者的症状完全缓解。在手术前，即使是基于磁共振成像的准确诊断也很困难，并且在组织学检查后才得以实现。手术是解决黄韧带血肿症状的一种治疗方法。
Study Design. A case report.Objectives. To understand a rare case of ligamentum flavum progressive hematoma.Summary of Background Data. Previously there were only two reports about ligamentum flavum hematoma.Methods. A patient was surgically treated for ligamentum flavum hematoma causing progressive L5 radiculopathy. Clinical and neuroradiologic features were reported, and the literature was reviewed.Results. The etiology of this case could not be defined except by minor back injury. In spite of conservative therapy, the symptoms were progressive for 7 months. Magnetic resonance imaging demonstrated the epidural mass lesion at L4-L5 that was continuous with the ligamentum flavum. The mass was hypointense in T1-weighted images and central hyperintense and marginal hypointense in T2-weighted images. The margin was well enhanced by Gd-DTPA administration. After removal of the mass lesion, the patient's symptoms completely resolved. Before surgery, accurate diagnosis was difficult even based on magnetic resonance imaging and was achieved after histologic examinations.Conclusions. Surgery could be a choice of the treatment modality to resolve symptoms in ligamentum flavum hematoma.
