A Case of Colorectal Villous Adenoma Found with PET-CT / 대한소화기내시경학회지

ABSTRACT

Adenomatous polyp in colorectal area is clinically important as being a precursor of colorectal cancer. Early detection of cancer reduces colorectal cancer mortality. Finding and removing precursor adenomas reduces colorectal cancer incidence especially in high risk groups. FDG-PET/CT is a new imaging technology in which a number of clinical applications has been recognized in oncologic imaging. FDG-PET has been shown to detect a wide variety of tumor foci including lymphoma, melanoma, lung cancer and colorectal cancer. Colorectal adenoma can also be detected by FDG-PET. In this case, we describe a colorectal villous adenoma, which was found by FDG-PET/CT. There was a mass of intensely increased FDG uptake in rectal area. The adenoma was confirmed with sigmoidoscopy and removed by polypectomy.
