Abstract

Our study aimed to evaluate the clinical characteristic and outcome of radiosurgery for post-operative high grade meningiomas. Methods: The authors reviewed records from 24 patients with histologically proven high-grade meningioma from July 2019 to July 2021. Patients were treated by stereotactic radiosurgery using Leksell Gamma Knife ICON unit (Elekta AB). We analyzed clinical, pre-clinical characteristics and local tumor control. Results: In our study, the mean age was 57,46 ± 14,49, male/female ratio was 1/2; 87,5% had neurological symptoms; 87,5% had atypical meningioma, 12,5% had anaplastic meningioma; 58,3% occur at the cerebral convexities. With an average follow-up time of 13 months (7-21 months), 2 grade II meningioma cases and 1 grade III meningioma case developed recurrence. The tumor control rate at 1 year was 94,1%. Conclusion: Gamma Knife radiosurgery is an effective method for local control of high-grade meningiomas.
