PRIMARY THORACIC INTRASPINAL HEMANGIOPERICYTOMA MIMICS MENINGEAL TUMOR:: A CASE REPORT AND LITERATURE REVIEW.

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 T8-T9 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. [ABSTRACT FROM AUTHOR]
