Objective : Hemangiopericytoma is known as a malignant tumor originating from pericytes and rarely occurs in the central nervous system. We present 6 cases of pathologically confirmed meningeal hemangiopericytoma. Methods : Retrospective study was done based on patient’s recordings including radiological studies. Each case of tumors was treated surgically and postoperative radiotherapy was done. Results : There were 5 cases of intracranial and 1 case of spinal hemangiopericytomas. Three of 5 intracranial hemangiopericytomas were located at tentorial region. Total tumor removal was done in 4 cases and postoperative local recurrence (or regrowth) was noted in 3 cases despite of postoperative external radiation therapy, 2 of which had died. Conclusion : Our cases show more frequent tentorial locations and poor clinical outcomes of hemangiopericytomas compared with meningiomas. KCI Citation Count: 1
