A 64-year-old woman had received radiotherapy, following surgery of a chromophobe pituitary adenoma. Six years after irradiation she began to complain of headache and dementia. Right vertebrogram demonstrated a right temporal mass lesion, stenosis and dilatation of middle cerebral artery and posterior, communicating artery in the field of irradiation. CT scan showed the irregular low density area at the right temporal region, and the irregular enhancement after an intravenous injection of contrast medium was seen at the small part of affected area. From these findings, radiation necrosis at the right temporal lobe was diagnosed. As vascular changes of the main cerebral arteries due to radiation are rare, we discussed on them from ever reported literature.
一名64岁女性在接受嫌色细胞垂体腺瘤手术后接受了放疗。放疗6年后，她开始抱怨头痛和痴呆。右侧椎动脉造影显示右侧颞叶有占位性病变，照射区域内大脑中动脉及后交通动脉狭窄和扩张。CT扫描显示右侧颞叶区域有不规则低密度区，静脉注射造影剂后，在病变区域的一小部分可见不规则强化。根据这些发现，诊断为右侧颞叶放射性坏死。由于放疗导致大脑主要动脉的血管变化很少见，我们根据以往报道的文献对其进行了讨论。
