The Appearance of Sjogren Syndrome on Ga-68-PSMA-11 PET/CT

摘要

Significant Ga-68-PSMA-11 activity is commonly observed in the lacrimal and salivary glands on PSMA PET/CT. An 80-year-old man after radical prostatectomy was evaluated with Ga-68-PSMA-11 PET/CT. There was no obvious PSMA uptake in the bilateral lacrimal, parotid, and submandibular glands. Subsequently, based on laboratory examination results and (TcO4)-Tc-99m salivary gland scintigraphy, this patient was diagnosed with Sjogren syndrome, which accounted for the absence of uptake by the glands. This case showed the potential of Ga-68-PSMA-11 PET/CT in the evaluation of the lacrimal glands and major salivary glands.
