Adenoid cystic carcinoma (ACC) is a rare and slow-growing tumor, originating from salivary glands. Locoregional recurrence and distant metastasis of ACC can be visualized not only with F-18-FDG but also with Ga-68-PSMA PET/CT due to its high prostate-specific membrane antigen (PSMA) expression. We report 2 cases of metastatic ACC who underwent first F-18-FDG and then Ga-68-PSMA for staging and restaging.
