Delayed radiation necrosis 7 years after gamma knife surgery for arteriovenous malformation--two case reports.

abstract：:We report a 30-year-old male case of an enlarged cerebellar arteriovenous malformation (AVM) associated with fenestration of the vertebral artery. Hemodynamic stress resulting from fenestration of the feeding system of AVM was probably an important factor in the enlargement of the small cerebellar AVM. ...
