Ligamentum flavum hematoma: a case report and literature review

摘要:

黄韧带血肿是一种罕见的椎管内硬膜外血肿，其发病机制尚不清楚，可能是由于轻微的外伤引起退变的黄韧带中增生的小血管破裂出血所致，最早由 Sweasey 于 1992 年报道，多见于腰椎，临床症状进行性加重，与椎间盘突出、滑膜囊肿等相似，主要表现为神经、硬膜囊受压的症状。本文报道了 1 例腰椎黄韧带血肿的病例，并对已发表文献回顾总结。

Abstract:

Ligamentum flavum hematoma is a rare spinal epidural hematoma with unclear pathogenesis, which may be caused by the rupture and bleeding of small blood vessels hyperplasia in degenerative ligamentum flavum caused by slight trauma. This disorder was first reported by Sweasey in 1992, and is mostly seen in lumbar spine, with progressive aggravation of clinical symptoms similar to disc hernia- tion and synovial cyst, and mainly manifested as symptoms of nerve and dural sac compression. Here, we report a case of lumbar ligamen- tum flavum hematoma and give a review of the published literature.
