Abstract

Metastatic jugular paraganglioma are rare tumors and account for less than 1% of the cases of head and neck tumors. We report a 40-year-old woman of jugular paraganglioma, presenting with right-sided neck swelling, hearing loss, and pulsatile tinnitus. Contrast-enhanced CT temporal bone revealed a mass in the right jugular foramina and extending inferiorly to internal jugular vein. Ga DOTANOC PET/CT was performed, which revealed somatostatin receptor expressing lesion in the right internal jugular vein and extension into sigmoid sinus and additional metastatic focus in the sacrum.

摘要

颈静脉部副神经节瘤是罕见的肿瘤，占头颈部肿瘤的比例不到 1%。我们报告了一例 40 岁的颈静脉部副神经节瘤患者，表现为右侧颈部肿胀、听力损失和搏动性耳鸣。增强 CT 颞骨显示右侧颈静脉孔有一肿块，向下延伸至颈内静脉。进行了 Ga DOTANOC PET/CT 检查，显示右侧颈内静脉有生长抑素受体表达的病变，并延伸至乙状窦和骶骨的另一个转移灶。
