摘　　要：<strong>Background:</strong> <span style="font-family:;" "="">Lumbar paraspinal hemangiopericytoma is rare. The hemorrhagic nature of the tumor causes problems of hemostasis and makes the resection delicate. We report a rare case of lumbar paraspinal hemangiopericytoma managed with preoperative embolization. <b>Clinical Case:</b> It is about a woman of 31 years, admitted for a large left lumbar paraspinal mass that evolved for 6 years. The clinical exam showed an asymmetry of the left paraspinal muscle. The mass painless was extended from the lumbar region. The neurological exam was normal. MRI showed the left large paraspinal mass tissue. It was extended from lumbar vertebrae, L1 to L4, and measured 100 </span><span style="font-family:;" "="">×<span> 50 </span>×<span> 50 mm. It was an iso-intense signal on T1-weighted with strong enhancement after gadolinium. It was hypervascular and supplied by left intercostal T12, L1, and L2 pedicles. The complete exclusion of the hyper-vascular left paraspinal tumor was obtained after selective embolization of the artery left L1 of the pedicle of the intercostal left L1 and trunks intercostal T12 and L2 left. The total resection of a mass encapsulated was performed. The operative outcome was good. The histology concluded to a hemangiopericytoma. No chemotherapy or radiotherapy was prescribed. After 5 years, the patient was asymptomatic. MRI control confirmed tumor resection with a residue at the level of the left intervertebral foramen L1</span></span><span style="font-family:;" "=""> </span><span style="font-family:;" "="">-</span><span style="font-family:;" "=""> </span><span style="font-family:;" "="">L2. <b>Conclusion:</b> Lumbar paraspinal hemangiopericytoma is an extremely rare tumor. Selective preoperative embolization is recommended before the resection of large tumors to reduce vascular supply. A follow-up extended for these patients is necessary, given the frequency of recurrences.</span><strong>Background:</strong> <span style="font-family:;" "="">Lumbar paraspinal hemangiopericytoma is rare.
