Familial adenomatous polyposis is a rare autosomal dominant intestinal syndrome with a high rate of malignant transformation. Here, we report a 20-year-old woman with a diagnosis of familial adenomatous polyposis by pathologic examination after colonoscopy biopsy, who underwent an 18F-FDG PET/CT to assess the extent of this disease. The images showed diffuse elevated FDG uptake along the entire colorectum. Additionally, focal enlarged lymph nodes with increased FDG uptake were noted. These findings promoted proctocolectomy and lymphadenectomy.
