OBJECT: The current study was undertaken to evaluate the @entity5 control rate and functional outcome after Gamma Knife surgery (GKS) in @entity1 with a @entity808 . The conditions associated with the development of @entity129 after radiosurgery were scrutinized. METHODS: The authors reviewed the clinical records and radiological data in 22 consecutive @entity1 who received GKS for a @entity808 . The median @entity5 volume was 4.1 ml (0.2-12.0 ml), and the mean @entity5 margin dose was 13.3 +/- 1.3 Gy at an isodose line of 49.9 +/- 0.6% (mean +/- standard deviation). The median clinical follow-up period was 46 months (range 24-89 months), and the median length of imaging follow-up was 37 months (range 24-79 months). RESULTS: @entity5 growth control was achieved in 21 (95%) of the 22 @entity1 . @entity158 responded best to radiosurgery, with two thirds of @entity1 showing improvement. However, only one third of @entity1 with @entity1183 improved. Six @entity1 (27%) experienced new or worsening @entity129 after GKS. Ten @entity1 (46%) showed @entity5 expansion after radiosurgery, and nine of these also showed central enhancement loss. Loss of central enhancement, @entity5 expansion, and a @entity5 in a cavernous sinus were found to be significantly related to the emergence of @entity129 . CONCLUSIONS: The use of GKS to treat @entity808 resulted in a high rate of @entity5 control and functional improvement. @entity129 are bothersome complications of radiosurgery, and @entity5 expansion in a cavernous sinus after radiosurgery appears to be the proximate cause of the complication. Loss of central enhancement could be used as a warning sign of @entity129 , and for this vigilant @entity1 monitoring is required.
