A 76-year-old man undergoing hormone therapy for prostate cancer was referred for 68 Ga-PSMA-11-PET (PSMA PET) due to persistently detectable PSA level. No PSMA-positive tumor lesions were detected, so a delayed phase imaging was performed, which revealed focal PSMA uptake in the right seminal vesicle together with contrast accumulation on excretory phase contrast-enhanced CT. These findings were finally determined to be secondary to urinary reflux as a consequence of a prostatic enucleation he had undergone 5 months earlier following an episode of acute urinary retention.
