目的：探讨下咽癌放射治疗后喉水肿的误诊原因及影像学特点。方法回顾性分析14例下咽癌放疗后喉水肿的患者误诊的临床资料。结果14例患者均诊断为下咽癌，其中9例伴有食管并颈部淋巴结转移，实行放射治疗。放疗结束后2～3个月，患者均出现呼吸困难加重症状，对症处理呼吸困难得到缓解，直至消失。3个月后MRI及喉镜复查均显示肿块消失，确定是喉水肿导致。随访12个月，未发现肿瘤复发或转移患者。结论对咽癌放射治疗后发生喉水肿的认识不足及对其MRI表现缺乏清楚的认识是误诊下咽癌放射性喉水肿的主要原因。

Objective To explore misdiagnosis and imaging features of laryngeal edema in hypopharyngeal after radiotherapy. Methods A retrospective analysis of clinical data of 14 patients with laryngeal edema in hypopharyngeal after radiotherapy was conducted. Results 14 patients were diagnosed as hypopharyngeal, including nine cases with esophageal and cervical lymph node metastasis 2~3 months after the end of radiotherapy, and they all had breathing dififculties. Three months later the MRI and laryngoscopy showed that the tumor was disappeared. During the follow-up of 12 months, there was no recurrence. Conclusion Lack of the aware of laryngeal edema pharyngeal cancer after radiation therapy is the main reason of misdiagnose.
