Multiple colorectal adenomas syndrome with malignant degeneration in multiple colorectal polyps: 18F-Fluorodeoxyglucose positron emission tomography–computed tomography findings

摘要

Multiple colorectal adenomas (MCRAs) syndrome is a genetic syndrome characterized by multiple colorectal polyps. Patients usually present late in late fourth or fifth decade of life. They have a high risk for developing malignancy. We here present such case of a 61-year-old man with MCRAs who developed malignant degeneration of multiple colorectal polyps, which was demonstrated on 18F-fluorodeoxyglucose positron emission tomography–computed tomography.
