Significant 68Ga-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 68Ga-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 99mTcO4 salivary gland scintigraphy, this patient was diagnosed with Sjögren syndrome, which accounted for the absence of uptake by the glands. This case showed the potential of 68Ga-PSMA-11 PET/CT in the evaluation of the lacrimal glands and major salivary glands.
68Ga-PSMA-11 在 PSMA PET/CT 中于泪腺和唾液腺呈现显著摄取。一名行根治性前列腺切除术的 80 岁男性接受了 68Ga-PSMA-11 PET/CT 检查。双侧泪腺、腮腺和颌下腺未见明显 PSMA 摄取。随后，基于实验室检查结果和 99mTcO4 唾液腺闪烁显像，该患者被诊断为干燥综合征，这解释了腺体摄取的缺失。该病例显示了 68Ga-PSMA-11 PET/CT 用于评估泪腺和大唾液腺的潜力。
