Objective To investigate the clinical efficacy of gamma knife in the treatment of cavernous hemangiomas in intracranial brain and to summarize the experience of gamma knife treatment. Methods Six cases of intracapsular cavernous hemangiomas located in the cavernous sinus were collected from May 2002 to May 2009. Four cases were treated with direct gamma knife, two cases with gamma knife after craniotomy. The average effective radiation The dose was 12.9 (11-16) Gy, and the optic nerve received less than 9.0 Gy (2.4-9.0 Gy). All cases were followed up for 6 months to 9 years. Results After the treatment of 5 cases of symptoms improved, 1 case still diplopia. MRI showed lesions disappeared in 1 case, reduced in 4 cases, no change in 1 case.
