Although rare, syncope may result from metastasis to the retropharyngeal or parapharyngeal space and involve or invade the glossopharyngeal nerve or internal carotid artery. We report the CT and MR imaging findings in four patients with syncope that preceded the diagnosis of recurrent squamous cell carcinoma in the pericarotid region. These findings suggest that recurrent carcinoma should be ruled out when a patient with head and neck malignancy and syncope is postoperatively examined.
虽然罕见,但晕厥可能由转移至咽后或咽旁间隙引起,并累及或侵犯舌咽神经或颈内动脉。我们报告了4例晕厥患者的CT和MR成像表现,这些患者在颈动脉周围区域复发性鳞状细胞癌诊断之前出现了晕厥。这些发现表明,对于头颈部恶性肿瘤且术后出现晕厥的患者进行检查时,应排除复发性癌。
