UNASSIGNED: @entity1756 of @entity5487 ( @entity5487 ) after radiotherapy for @entity5513 ( @entity5513 ) are rare, and no definite treatment has been established for distal @entity5487 @entity2849 . We describe a 61-year-old @entity1 who underwent Gamma Knife surgery (GKS) for left @entity5513 . Follow-up magnetic resonance imaging (MRI) revealed partial regression of the @entity5 . Twelve years after GKS, he suffered from @entity510 . Initial angiogram showed no @entity455 ; second left vertebral angiogram, 10 days after admission, demonstrated a @entity2849 in the lateral pontine segment of the left @entity5487 . The proximal portion of the @entity5487 was occluded by a coil. Postoperative MRI revealed an @entity1188 on the left side of the pons and brachium pontis. Although the @entity1 suffered from mild @entity6447 , he was discharged 1 month postoperatively requiring no assistance with activities of daily living. Twelve months later, he recovered satisfactorily with a modified Rankin Scale grade of 1, and no recanalization of the @entity439 was found on MR angiography. Endovascular parent artery occlusion for @entity1756 at distal @entity5487 carries the risk of @entity11401 , but should be considered when no other option is available such as after radiotherapy for @entity5513 .
