The Diagnosis And Therapy Of Hemangiopericytoma Of Central Nervous System

Objective To study the diagnosis and therapy of hemangiopericytoma of central nervous system. Methods The analysis of 12 cases of hemangiopericytomas of central nervous system hospitalized in affiliated 2^nd hospital of Zhejiang University since 2003 was carried out and a review of relevant literature was done. Results The average age of patients with primary was 42. 4 year-old. The ratio of male to female was 2: 1. Among the 12 cases, 4 cases are recurrent. Total tumor removal was achieved in 9 cases , and subtotal removal in 3 cases. 8 patients received postoperative radiotherapy. 10 patients were followed up from 9 month to 47 months (average 27 months). During the follow-up period, one patient died of recurrence and the others returned to theirprevious jobs or could live independently. Conclusion HPC is difficult to differentiate with the meningioma preoperatively. Surgical management is the best choice for treatment of patients with HPC. Postoperative radiotherapy can postpone the risk of tumor recurrence.
