Figure 3: (A,B): A 60-year-old man treated with surgery for low rectal cancer presented with bleeding per rectum and underwent an FDG PET / CT study. Axial unenhanced CT scan (A) shows ill-defined soft tissue thickening in the perianal region (arrow) without definite evidence of a nodule / mass. Fusion PET / CT image (B) shows an intense focus of hypermetabolism corresponding to the soft tissue thickening, suggesting perianal recurrence
