Figure 2 Results of positron emission tomography-computed tomography (PET-CT) and colonoscopy. A: Colonoscopy results indicated a lower rectal swelling, with a red and smooth surface located at 3 cm on the top of the anal verge, which suggested a submucosal tumor; B: Upper left part: local destruction of the bone cortex; lower left part: PET-CT images depicting uptake of fluorodeoxyglucose (FDG) within the left acetabulum, with the maximal standardized value of uptake (SUVmax) equal to 5.5; C: PET-CT image depicting FDG uptake in the distal rectum, with SUVmax 11.2.
