Hemangiopericytoma (HPC) has been described to be aggressive and potentially a malignant tumour. We report a rare case of a 63-year-old Chinese male who presented with primary intradural extramedullary HPC of the thoracic spine. The main presenting complaint was gradual progression of back pain, associated with paraparesis and sensory deficit of lower limbs. He had MRI thoracolumbar with contrast which showed T9 lesion compressing on spinal cord and oedema, he was then operated upon and histopathology report confirmed a thoracic spine HPC. A T8/9 laminectomy and excision of intradural extramedullary lesion was performed, tumour section was sent for frozen section study, and more tissue was sent for paraffin studies and additional immunohistochemical staining. Surgical resection is most commonly performed, radiotherapy remains debatable. In this report, we discussed another rare case of primary spinal HPC to be added into the literature.
血管外皮细胞瘤（HPC）被认为具有侵袭性，可能是一种恶性肿瘤。我们报告一例罕见病例，一名63岁中国男性，患有胸椎原发性硬脊膜内髓外HPC。主要就诊主诉是背痛逐渐加重，伴有双下肢轻瘫和感觉障碍。他接受了胸腰椎增强MRI检查，结果显示T9病变压迫脊髓并伴有水肿，随后接受手术，组织病理学报告证实为胸椎HPC。进行了T8/9椎板切除术并切除硬脊膜内髓外病变，肿瘤切片送去做冰冻切片研究，更多组织送去做石蜡研究和额外的免疫组化染色。手术切除是最常用的方法，放疗仍存在争议。在本报告中，我们讨论了另一例罕见的原发性脊柱HPC病例，以补充到文献中。
