Metastases From Colorectal Cancer Avid on 68Ga-PSMA PET/CT

Abstract: 68Ga-PSMA PET/CT is currently used for detection of prostate cancer including metastases, even at low prostate-specific antigen values. A grown number of reports have shown increased uptake of PSMA in neovessels of nonprostatic malignancies including lung cancer, and recently a case report has demonstrated increased PSMA uptake in colorectal adenocarcinoma. In this case report, we demonstrate increased 68Ga-PMSA uptake on PET/CT in metastases from previously treated colon adenocarcinoma, and it illustrates the importance of histology of suspicious lesions on 68Ga-PSMA PET/CT.
