摘　　要：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.
