We report the case of a 34-year-old @entity1 who exhibited acute deterioration in her condition after cerebral angiography for evaluation of a large @entity1653 . She had undergone surgery and irradiation for a @entity11 in the right occipital lobe 23 years before this episode. She experienced incapacity at work. On @entity7994 , a large @entity1653 was detected on the left frontal convexity; this @entity5 was thought to be radiation-induced. Cerebral angiography was performed to assess the vascularization of the @entity5 . Her condition began to deteriorate 2.5 h after the cerebral angiography. CT revealed an increase in the mass of the @entity5 , and a high density area in the @entity5 . We immediately removed the @entity5 . Histopathological examination revealed the @entity5 to be a @entity1653 . New @entity548 foci were identified in the @entity5 . In addition, macrophages containing hemosiderin were detected, and some of the @entity5 vessels exhibited @entity528 . We suspected that angiography triggered @entity548 in the @entity1653 , which was already predisposed to @entity548 .
