FDG PET/CT in Peritoneal Metastasis From Prostate Cancer

Abstract

Prostate cancer is one of the leading causes of cancer death in men. The prognosis in prostate cancer is greatly worsened by the presence of metastases, which are most commonly found in bone, lung, liver, and brain. The peritoneum is an extremely uncommon metastatic site for prostate cancer, even in autopsy series. We present a case of FDG PET/CT demonstration of peritoneal metastasis from prostate cancer.

Detection of Diffuse Peritoneal and Omental Metastases From Prostate Cancer With 18F-PSMA-1007 PET/CT

“…In published cases, either 18 F-FDG or 68 G-PSMA was used as tracers for PET/CT imaging. Furthermore, most previous imaging findings only showed isolated peritoneal or omental metastasis with local 4 or multinodular infiltration 7 . Diffuse peritoneal and omental infiltration of prostate cancer detected by 18 F-PSMA-1007 PET/CT was rarely reported.…”

“…The most common metastatic sites for prostate cancer are skeletal system and lymph nodes, but extremely rare involvement of peritoneum or omentum. There are limited cases of peritoneal or omental metastasis secondary to prostate cancer published in the literature 4–7 . In published cases, either 18 F-FDG or 68 G-PSMA was used as tracers for PET/CT imaging.…”
