The primary treatment of nasopharyngeal carcinoma (NPC) has been external radiotherapy. Rupture of an internal carotid artery (ICA) pseudoaneurysm is a rare complication of irradiation therapy for a nasopharyngeal carcinoma. A 78 years old man had a history of NPC treated with radiotherapy in 1993. He was admitted to the hospital because of epistaxis. Angiography showed an ICA pseudoaneurysm pointing medially to the nasopharynx. Coil embolization of the ICA was performed, but cerebral infarction occurred. Internal carotid artery (ICA) pseudoaneurysms are an uncommon but potentially lethal condition. Angiography is the mainstay of diagnosis of the aneurysm and planning the embolization of the ICA. We should be more aware of this complication in NPC patients.
鼻咽癌（NPC）的主要治疗方法一直是外照射放疗。颈内动脉（ICA）假性动脉瘤破裂是鼻咽癌放射治疗的一种罕见并发症。一名78岁男性有1993年接受鼻咽癌放疗的病史。他因鼻出血入院。血管造影显示一个向鼻咽内侧突出的ICA假性动脉瘤。对ICA进行了弹簧圈栓塞，但发生了脑梗死。颈内动脉（ICA）假性动脉瘤是一种罕见但可能致命的疾病。血管造影是诊断动脉瘤和规划ICA栓塞的主要手段。我们应该更加关注鼻咽癌患者的这种并发症。
