title: [Diagnosis and treatment of intracranial hemangiopericytoma].
abstract: OBJECTIVE
  To summarize the experience in diagnosis and treatment of intracranial hemangiopericytoma (HPC).
  
  
  METHODS
  The clinical data of 63 patients, 37 males and 26 females, aged 41 (14 - 77), with intracranial HPC were studied retrospectively.
  
  
  RESULTS
  Fifty-eight patients underwent total excision of tumor and 5 patients underwent subtotal excision. Thirty-eight patients were followed up for 3 to 84 months (on average: 25 months), of which 34 underwent conventional external beam radiotherapy as an adjuvant measure after the first operation. Six patients who had local recurrence received second operation. Two patients had metastases to the spine.
  
  
  CONCLUSIONS
  Complete excision followed with radiotherapy can delay the recurrence of HPC, a malignant tumor with rich blood supply, and improve the prognosis. Pre-operative embolization of the feeding artery may be helpful to the surgery and abundant transfusion should be ready intra-operatively.
