Leksell Gamma Knife was used to treat 66 patients with glomus jugulare tumour at 6 European sites between 1992-1998. The age of the patients ranged between 18-80 years (median 54 years). Gamma Knife radiosurgery was a primary treatment in 30 patients (45. 5%). Open surgery preceded radiosurgery in 24 patients (36.4%), embolisation in 14 patients (21.2%) and fractionated radiotherapy in 5 patients (7.6%). The volume of the tumour ranged 0.5-27 cm(3) (median 5,7 cm(3)). The minimal dose to the tumour margin ranged between 10-30 Gy (median 16.5 Gy). After radiosurgery 52 patients were followed, the follow up period was 3-70 months (median 24 months). Neurological deficit improved in 15 patients (29%) and deteriorated in 3 patients (5,8%), one transient and two persistant. Neuroradiological follow up using MRI or CT was performed in 47 patients 4-70 months (median 24 months) after radiosurgery. Tumour size decreased in 19 patients (40%) while in the remaining 28 patients (60%) no change in the tumour volume was observed. None of the tumours increased in volume during the observation period. Control angiography was performed in 6 patients. Pathological vascularisation completely disappeared in one patient, reduced in two and there was no change in the remaining three. Radiosurgery proves to be a safe treatment for glomus jugulare tumour with no mortality and no acute morbidity. Because of its naturally slow growth rate, up to 10 years of follow up will be necessary to establish a cure rate after radiosurgery for these lesions.

We have treated 14 patients with glomus tumor during the 4 years (of 1993 to 1997) using Leksell Gamma Knife radiosurgery. The male: female ratio was 1:3.7, and the mean age 48.6 years (range 22-75 years). The mean tumor volume was 5.5 cm3 (range 0.7-11.3 cm3). The mean maximum dose was 37.4 Gy (range 20-44 Gy). The mean margin dose was 19.4 Gy (range 10-25 Gy). In 3 patients, infrabasal spread of the tumor could not be delineated on peroperative stereotactic CT scans. As a result, this portion of the tumor was treated in 2 patients at a second stage using stereotactic MRI. Follow-up in 11 patients ranged from 6 to 42 months (mean 20.5 months). Hearing on the affected side was further impaired in 3 patients. Tinnitus, vertigo and ataxia improved in 3 patients, headache and nausea in 2 patients. Angiography after radiosurgery was performed in 3 patients. In one patient 12 months after the radiosurgery, pathological vascularisation had completely disappeared. In another patient pathological vascularisation was still present 22 months after the first stage, despite two-stage radiosurgery, although the tumor volume decreased 30%. In the last patient, vascularisation and tumor volume partially decreased 12 months after radiosurgery. The volume of the tumor decreased in 4 patients. No change in tumor volume has been observed in any of the other patients to date. Radiosurgery proves to be a safe treatment for glomus tumor with no acute morbidity. Because of its naturally slow growth rate, up to 10 years follow-up will probably be necessary to establish the therapeutic effectiveness of radiosurgery for glomus tumor.
