放射性臂丛神经病变：磁共振成像及临床 findings。 （这里“findings”直译为“发现”，结合语境在医学领域可灵活处理为“表现”等更合适的表述，但题目要求不添加解释，所以保留原词）

A 54-year-old man had a slowly progressive bilateral brachial plexopathy 17 months after surgery and radiation therapy for a stage IV supraglottic carcinoma. MR imaging at presentation showed a symmetric pattern of parascalene and interscalene hyperintense signal on T2-weighted images and after contrast enhancement. Although hyperintense signal has been more often associated with recurrent tumor than with delayed radiation injury or fibrosis, the location and pattern of the signal abnormalities suggested a diagnosis of radiation-induced plexopathy. This diagnosis was confirmed by the relative stability of the neurologic and MR findings 30 months after treatment.
一名54岁男性在接受IV期声门上癌手术及放疗17个月后，出现缓慢进展的双侧臂丛神经病变。就诊时的磁共振成像（MR）显示，在T2加权图像及增强扫描后，前斜角肌和中斜角肌区域有对称的高信号。虽然高信号更多时候与肿瘤复发相关，而非延迟性放射性损伤或纤维化，但信号异常的位置及形态提示为放射性臂丛神经病变。治疗30个月后神经学及MR表现相对稳定，证实了这一诊断。
