    Abstract:
    We have treated three patients with conventional radiotherapy and one with stereotactic radiosurgery and report the follow-up results. Case 1 was of a 63-year-old woman who had a dural AVM in the right cavernous sinus. She was irradiated using 10MV X-rays with a total of 30Gy. Post irradiation angiography showed a complete absence of dural AVM. Case 2 was of a 62-year-old woman who had a dural AVM fed by the left external carotid artery in the right cavernous sinus. Embolization by gelfoam was performed before irradiation. The irradiation was given with a total dose of 30Gy. Post irradiation angiography showed disappearance of the dural AVM. Case 3 was of a 26-year-old woman who had a small AVM (about 20 x 15 x 15mm) in the posterior corpus callosum. An operation was performed but the AVM was not excised completely. We irradiated the residual AVM with a total of 30Gy. The follow-up angiography one year after treatment, showed disappearance of the AVM. She had no neurological deficit two years after the treatment. Case 4 was of a 14-year-old boy who had a small AVM (about 20 x 15 x 10mm) in the left anterior wall of the fourth ventricle. The AVM was located deeply, so an operation was not performed. Radiosurgery was undertaken four months after onset in Buenos Aires. The total dose was 36Gy. The follow-up angiography one year after treatment, showed disappearance of the AVM. He also had no neurological deficit two years after the treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
