abstract: OBJECTIVE
  To explore the genesis and classification and diagnosis as well as the treatment of multiple meningiomas.
  
  
  METHODS
  Retrospective study of the materials of 32 cases of multiple meningiomas, simultaneously review of the related articles.
  
  
  RESULTS
  All patients were divided into 5 groups, primary 18 cases, postoperative 7 cases, accompanied by neurofibromatosis (NF) 4 cases, meningiomatosis 1 case, accompanied with other intracranial tumor 2 cases, one with pituitary adenoma and the other with glioma. All the patients accepted operation, cured 25 cases, improved 7 cases.
  
  
  CONCLUSIONS
  The cytogenesis of different type of multiple meningiomas probably varied. Estrogen may play an important role in the genesis of multiple meningiomas. One stage resection of all the tumors was feasible to most cases and advocated. Most cases had strong tolerance to several times of operation, staging operation was permitted. The prognosis and principle of treatment of different group varied.
