title: [Therapeutic effect of gamma knife on intracranial cavernous angioma].
abstract: OBJECTIVE
  To evaluate the therapeutic effect of gamma knife on patients with intracranial cavernous angioma (CA).
  
  
  METHODS
  The medical records of 122 patients (134 lesions) who underwent radiosurgery were reviewed retrospectively.
  
  
  RESULTS
  Th e average follow-up period was 43 months. No patient died. One patient underwent CA resection. In patients with epilepsy, 83% patients showed alleviation of seizures. About 44% of the lesions shrank in size after treatment with gamma knife radiosurgery (59/134). Seven cases had hemorrhage again after radiosurgery, and the overall annual hemorrhage rate was 1.6%. Edema was found in 11.5% patients (14/122) and all patients showed improvement aft er treatment.
  
  
  CONCLUSIONS
  Gamma knife is a safe treatment for CA, which could obviously improve the symptoms of epilepsy. Gamma knife radiosurgery is the fi rst option for the treatment of cavernous sinus angiomas.
