累及棘突多发胸椎血管瘤:1例报告与文献综述

Multiple thoracic hemangiomas involving spinous processes: a case report and literature review

摘要:

脊柱血管瘤(vertebral hemangioma, VHs)是一种常见的脊柱良性肿瘤，大多无症状。只有 0.9%~1.2% 的侵袭性 VHs 由于骨膨胀、皮质侵蚀、向椎管内延伸、血流障碍、硬膜外出血导致脊髓、神经根压迫而引起神经症状。此外，脊柱血管瘤也会导致严重的并发症，如脊柱病理性骨折。本文报告了 1 例累及棘突多发胸椎血管瘤，且伴有相邻节段的椎体病理性骨折，并回顾总结已发表累及棘突的脊柱血管瘤的文献回顾总结。

Abstract:

Vertebral hemangiomas (VHs) are common benign tumors that are mostly asymptomatic. Only 0.9%~1.2% of invasive VHs have neurological symptoms due to compression of the spinal cord, nerve roots, or both due to bony swelling, cortical erosion, extension into the spinal canal, impaired blood flow, and epidural hemorrhage. In addition, VHs can lead to serious complications sometimes, such as patho- logical fractures of the spine. This article reports a case of multiple thoracic hemangiomas involving the spinous process complicated with pathological fractures of the involved segment and the adjacent segment, and summarizes the published literature on VHs involving the spi- nous process.
