Figure 9: (A,B): A 59-year-old man who underwent an abdominoperineal resection for low rectal cancer came for follow-up. An FDG PET / CT image (A) reveals a focus of abnormal FDG uptake at the colostomy site (arrow). Close inspection of the CT scan (B) reveals an inconspicuous soft tissue nodule (arrow) corresponding to the increased FDG uptake, suggesting recurrence at the colostomy site. Postoperative changes in the anterior abdominal wall can often mask such recurrent nodules, which are detected on PET, by virtue of their hypermetabolism.
