Sy Ortin [and three others] The outcome of radiosurgery performed on tumors and arteriovenous malformations are presented. A retrospective review was conducted on 92 cases treated at Makati Medical Center. Seventy patients were treated for neoplasms while 22 patients were treated for arteriovenous malformations. Of the 37 tumor cases with radiographic follow-up, 2 disappeared, 16 decreased in size, 9 increased in size, and 10 showed no change. Seventeen cases had central necrosis. Clinical outcome was favorable in 60% of patients. Three AVM cases met the minimum angiographic follow-up of 1 year. Of these, two decreased in size, one had incomplete obliteration. In another case of an AoVM, the lesion was no longer visualized on subsequent MRI. Clinical outcome was favorable in all cases. Results of this study are encouraging: 75.6% tumor growth control was achieved for tumors while 75% decrease in nidus size and 25% disappearance of the nidus was achieved for AVMs. Makati Medical Center Proceedings, 1999 (13) pages 47-56 Radiosurgery Retrospective Studies Intracranial Arteriovenous Malformations pathology Magnetic Resonance Imaging Ortin, Teresa T.
