CONTEXT
Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare.
CASE REPORT
We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented with progressive back pain over a four-month period that progressed to paraparesis, bilateral leg paresthesia and urinary incontinence. The surgical intervention involved laminectomy and subtotal resection of the tumor, with posterior vertebral fixation. Postoperative involved-field radiotherapy was administered. A marked neurological improvement was subsequently observed. We describe the clinical, radiological, and histological features of this tumor and review the literature.
背景
血管外皮细胞瘤是一种罕见的间叶性肿瘤，很少累及椎管。脊柱原发性恶性血管外皮细胞瘤极为罕见。
病例报告
我们报告一例21岁男性的胸椎原发性硬膜外恶性血管外皮细胞瘤，该肿瘤侵犯椎骨并导致脊髓受压。患者在四个月内出现进行性背痛，进而发展为双下肢轻瘫、双侧腿部感觉异常和尿失禁。手术干预包括椎板切除术和肿瘤次全切除术，并进行后路椎体固定。术后进行了受累野放疗。随后观察到明显的神经功能改善。我们描述了该肿瘤的临床、放射学和组织学特征，并复习了相关文献。
