ABSTRACT

ObjectiveTo study the clinical effects of X-kn ife in the treatment of intracranial meningiomas.MethodsA retrospective analysis of 52 cases of intracranial meningioma treated by X-knife was made. The peripheral dose was (10 ～20) Gy, with a mean of 13 Gy. Follow-up checkups consisted of clinical examina tions and contrast-enhanced CT scans.ResultsAfter the treatm ent, unilateral m ild hemiplegia occurred in 1 case (1 9%) and local epileptic attack occurred in 2 cases (3 8%). Imaging findings revealed asymptomatic transient peritumoral ed e ma in 12 cases (23 1%). Follow-up imaging lasting (3～92) months (mean, 23 mont hs ) in 40 cases (76 9%) found regression of tumor in 18 cases (45 0%) and unchan ge d tumor size in 22 cases (55 0%).ConclusionsX-knife is an e ffective and safe procedure for meningiomas.
