title: [Diagnosis and treatment of cystic meningioma].
abstract: OBJECTIVE
  To explore the pathogenetic mechanism of cystic meningioma and the key to its diagnosis and operation.
  
  
  METHODS
  Clinical data of 8 patients with cystic meningioma were analyzed retrospectively. The occuring position and cure rate of cystic meningioma were compared with those of solid meningioma in the corresponding period.
  
  
  RESULTS
  All patients were subjected to total resection of tumor parenchyma and cystic wall. No operative death and severe complications occurred. The incidence of uppertentorial region of cystic meningioma was higher than that of solid meningioma, and the difference was significant (χ(2)=2.618, P<0.05). The cure rate was not significantly different between cystic meningioma and solid meningioma (χ(2)=0.010, P>0.05).
  
  
  CONCLUSIONS
  Removing tumor totally is the key to preventing its recurrence.
