Increased Prostate-Specific Membrane Antigen Uptake in a Gallbladder Stone

Clin Nucl Med. 2024 Apr 1;49(4):344-345. doi: 10.1097/RLU.0000000000005121. Epub 2024 Feb 28.

Abstract

An Al 18F-prostate-specific membrane antigen (PSMA) Q PET/CT scan was performed in a 67-year-old man to identify any potential recurrent prostate cancer lesions, which revealed no recurrent or metastatic lesions. However, a large gallbladder stone with increased PSMA uptake was incidentally detected, which could be a potential pitfall in the interpretation of PSMA PET imaging.
