Abstract

We report a case of biopsy-proven prostate cancer metastasis to the rectum and presumed metastasis to a mesorectal lymph node, identified as radiotracer-avid lesions on prostate-specific membrane antigen PET/CT during workup for biochemically recurrent prostate cancer. This case adds to a growing number of atypical sites of metastatic prostate cancer being reported since the approval of prostate-specific membrane antigen PET/CT for staging of prostate cancer.
