Abstract:
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.
