Abstract

Introduction: This case highlights the rare but life-threatening complication of carotid blowout syndrome (CBS) after radiotherapy for nasopharyngeal carcinoma (NPC). It is characterized by rupture of the carotid artery, often occurring months or years after treatment. Early diagnosis and timely intervention are essential to improve clinical outcomes.

Case presentation: A 45-year-old woman with NPC developed recurrent epistaxis 31 months after chemoradiotherapy. MRI and MRA ruled out tumor recurrence. High-resolution vessel wall imaging (VWI) revealed eccentric thickening, irregular enhancement, and a pseudoaneurysm in the lacerum segment of the left internal carotid artery (ICA), which was confirmed by CTA and DSA. The patient underwent embolization and remained stable at 1-year follow-up.

Conclusion: This case underscores the value of VWI in detecting CBS-related vascular changes. Imaging is crucial for early diagnosis and timely intervention in high-risk patients with NPC who have undergone radiotherapy.

鼻咽癌放疗后颈动脉爆裂综合征的影像学分析。

本病例强调鼻咽癌（NPC）放疗后罕见但危及生命的颈动脉爆裂综合征（CBS）并发症。其特征是颈动脉破裂，常在治疗后数月或数年发生。早期诊断和及时干预对改善临床结果至关重要。病例介绍：一名45岁女性鼻咽癌患者在放化疗31个月后复发性鼻出血。MRI和MRA排除肿瘤复发。高分辨率血管壁成像（VWI）显示左侧颈内动脉（ICA）撕裂段偏心增厚，不规则强化，假性动脉瘤，经CTA和DSA证实。患者接受了栓塞治疗，并在1年的随访中保持稳定。结论：本病例强调了VWI在检测cbs相关血管病变中的价值。影像学对高危鼻咽癌放疗患者的早期诊断和及时干预至关重要。
