Primary thoracic intraspinal hemangiopericytoma mimics meningeal tumor

Hemangiopericytoma (HPC) accounts for less than 1% of all central nervous system tumors and is particularly rare in the spinal canal. HPC mimics other CNS intradural tumor radiologically. We present a rare case of intraspinal HPC initially diagnosed as thoracic intraspinal meningeal tumor radiologically. The patient was treated with T8T9 partial laminectomy and en bloc tumor removal. Radiation therapy for tumor bed was prescribed. The patient had symptom recovery postoperatively, and remained free from local recurrence in the 3 years follow-up. Literature reviews focused on tumor behavior and treatment policy.
