title: [Intracranial hemangiopericytoma 32 cases reports].
abstract: OBJECTIVE
  To further elucidate the clinical feature, pathogenesis, treatment and prognosis of intracranial hemangiopericytomas (HPC).
  
  
  METHODS
  Thirty-two cases of HPC treated in our department were analyzed retropectively.
  
  
  RESULTS
  Grade I surgery, complet tumor removal with excision of involved dural and bone (7 cases); Grade II surgery, complet tumor removal with aggressively cauterization of dural and/or bone (13 cases); Grade III surgery, complet tumor removal but no satisfactory attempt to deal with involved dural or bone (7 cases); Grade IV surgery, tumor residual (7 cases). 13 cases were recurrent.
  
  
  CONCLUSIONS
  The prognosis of intracranial hemangiopericytomas is dismal. The recurrent rates of HPC are very high. Microneurosurgery and adjuvant radiotherapy are main treatment. It is very important that counterchecking at regular intervals.
