The neurologist decided to perform dopamine transporter imaging (18F-FP-CIT PET/CT) for accurate diagnosis, taking into account the potential adverse effects of l-dopa that the patient had been taking for a long time. The uptake of dopamine transporter in the bilateral basal ganglia was well preserved, but reduced uptake in the left parotid gland was incidentally detected. A subsequent salivary scan showed reduced uptake in the left parotid gland with the same pattern as that on 18F-FP-CIT PET/CT. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
