A 29-year-old woman, who had undergone stereotactic radiosurgery for a pontine arteriovenous malformation, experienced sudden onset of facial nerve palsy with trigeminal nerve disturbance 19 months after irradiation. Magnetic resonance imaging revealed significant radiation-induced edema surrounding the nidus. Angiography demonstrated total obliteration of the arteriovenous malformation 24 months after irradiation. Further magnetic resonance imaging studies, performed 28 months after treatment, showed that, despite the persistence of symptoms, the radiation-induced edema had subsided.
一名29岁女性因脑桥动静脉畸形接受了立体定向放射治疗，放疗19个月后突然出现面神经麻痹并伴有三叉神经功能障碍。磁共振成像显示病灶周围有明显的放射性水肿。血管造影显示放疗24个月后动静脉畸形完全闭塞。治疗28个月后进行的进一步磁共振成像研究表明，尽管症状持续存在，但放射性水肿已消退。
