Abstract:
We present the case of a 45-year-old woman with known adenoid cystic carcinoma of the right parotid gland, postexcision and postoperative radiation therapy. She was followed up on 18F-FDG PET/CT, which revealed minimal local residual disease and bilateral lung nodules, for which chemotherapy was initiated. Postchemotherapy, 18F-FDG PET/CT showed residual lung metastases. As a part of ongoing project, 68Ga-PSMA PET/CT done revealed additional focal uptake in the right cerebellum, missed on FDG PET/CT. The brain lesion was confirmed upon MRI.
