Enhancement in the region of the jugular foramen on magnetic resonance imaging (MRI) is highly sensitive to the presence of a skull base neoplasm. Unfortunately, this imaging method lacks the specificity to be the sole criterion in the diagnosis of a lesion of the jugular foramen. Although well described in the radiological literature, the phenomenon of gadolinium enhancement of the relatively static blood in the jugular system continues to be erroneously diagnosed as glomus jugulare tumor. Instances of this phenomenon present in patients referred to our practice for surgical opinions before radiation therapy and/or definitive resection will be presented. The purpose of this communication is to bring this potential treatment pitfall to the attention of the neurotology community. Treatment planning for lesions of the lateral skull base cannot singularly be based on MRI findings but requires a healthy skepticism satisfied only by more complete evaluation.
磁共振成像（MRI）上颈静脉孔区域的强化对颅底肿瘤的存在高度敏感。不幸的是，这种成像方法缺乏特异性，不能作为诊断颈静脉孔病变的唯一标准。尽管在放射学文献中有详细描述，但颈静脉系统中相对静止血液的钆强化现象仍被错误地诊断为颈静脉球瘤。本文将介绍在接受放射治疗和/或确定性切除术前前来我们科室寻求手术意见的患者中出现这种现象的病例。本文的目的是引起耳神经学界对这一潜在治疗陷阱的关注。外侧颅底病变的治疗计划不能仅基于MRI结果，而需要通过更全面的评估来满足健康的怀疑态度。
