【 摘 要 】

The inguinal lymph nodes are an unusual site of metastases for prostate adenocarcinoma. We present a case in which a 61-y-old man with biochemically recurrent prostate cancer underwent attenuation-corrected 11C-acetate PET/CT, which demonstrated multiple foci of increased activity in the left inguinal, left iliac chain, and right inguinal regions. The attenuation-corrected CT portion of the scan also showed anterior wall thickening of the rectum. The imaging findings were suggestive of metastatic involvement of the rectum below the dentate line with subsequent spread to the inguinal lymph nodes.
