Advanced adenoma diagnosis with FDG PET in a visibly normal mucosa: a case report.

Background: An accurate, early diagnosis and treatment of adenomatous polyp can curtail progression to colorectal cancer. F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET) reveals the biochemical changes associated with the development of many cancers which precede the appearance of gross anatomical changes that may be visualized during surgical resection or via imaging with MR or CT.

Intervention: We detail the history of a 64 year old female who had a whole-body FDG PET scan as a part of an employee wellness program.
