Intense fluoro-2-deoxyglucose uptake in high-grade prostatic adenocarcinoma with negligible prostate-specific...

While ⁶⁸Gallium prostate-specific membrane antigen positron emission tomography/computed tomography (⁶⁸Ga-PSMA) has demonstrated increasing utility in the evaluation of prostatic carcinoma, it is essential to be aware of false-negative findings. Further subtype analyses of prostate cancer will be helpful in the understanding of the underlying reasons. We herein present a high-grade prostate adenocarcinoma, with metastatic lesions showing high ¹⁸F-labeled fluoro-2-deoxyglucose uptake instead of 68Ga-PSMA.
