Mild 68 Ga PSMA-11 Uptake in Incidental Pituitary Adenoma

[摘要] A 76-year-old man with metastatic prostate cancer was referred to 68 Ga prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) for restaging. A consecutive 18 F-fluorodeoxyglucose (FDG) PET/CT was performed due to the history of lung cancer in the left lung treated with stereotactic radiotherapy. Intense 18 F-FDG uptake was detected in the pituitary gland despite the mild uptake of 68 Ga PSMA. Contrast-enhanced magnetic resonance imaging confirmed pituitary adenoma.
