FIGURE 1. Focal 18F-FDG uptake in 57-y-old woman who had undergone total gastrectomy for stomach cancer and was being evaluated for fatigue, abdominal pain, frequent vomiting, equivocal endoscopic findings at level of anastomosis, and negative findings on whole-body CT. (A) From left to right, coronal, sagittal, and transaxial PET slices show focus of increased 18F-FDG uptake (arrows) in left lower abdomen. (B) Area of increased uptake (arrows) was localized by PET/CT (left panel) to small bowel, as seen on corresponding CT image (right panel). PET/CT-guided surgery revealed small-bowel metastasis originating from primary gastric cancer. No abnormal 18F-FDG uptake was seen in region of anastomosis, and there was no further evidence of disease in this area.
