The occurrence of metastatic tumor in the internal auditory canal is very rare. Thus, we report FDG PET/CT findings of bilateral Internal auditory canal metastasis from lung cancer in a 67-year-old man. FDG PET/CT and MRI showed nodules in the bilateral internal auditory canal with an SUV max of 5.2. This case hints us that bilateral metastasis should be considered as differential diagnosis when we encounter bilateral nodule in the internal auditory.
内耳道出现转移性肿瘤非常罕见。因此，我们报告了一名67岁男性肺癌双侧内耳道转移的FDG PET/CT检查结果。FDG PET/CT和MRI显示双侧内耳道有结节，最大标准摄取值（SUV max）为5.2。该病例提示我们，当在内耳道遇到双侧结节时，应将双侧转移作为鉴别诊断的考虑因素。
