Figure 2 Peritoneal carcinomatosis detected only on contrast-enhanced computed tomography in a 46-year-old woman who underwent gastrectomy for advanced gastric cancer 17 mo prior. A: Contrast-enhanced abdominal computed tomography shows enhanced peritoneal thickening (arrow) with ascites. Peritoneal metastasis was confirmed by histological analysis of ascitic fluid. B: Positron emission tomography/computed tomography image at the same level without evident hypermetabolism in the peritoneum.

Figure 3 Locoregional recurrence detected on both contrast-enhanced computed tomography and positron emission tomography/computed tomography in a 76-year-old woman who underwent gastrectomy for advanced gastric cancer 21 mo prior. A: Contrast-enhanced abdominal computed tomography shows enhanced wall thickening (arrow) at the anastomotic site; B: Positron emission tomography/computed tomography image at the same level shows hypermetabolism at the anastomotic site.

Figure 4 Lymph node recurrence detected on both contrast-enhanced computed tomography and positron emission tomography/computed tomography in a 73-year-old man who underwent gastrectomy 18 mo prior. A: Contrast-enhanced abdominal computed tomography shows enlarged lymph nodes at the aortocaval and para-aortic spaces; B: Positron emission tomography/computed tomography image at the same level shows hypermetabolism at the aortocaval and para-aortic spaces.

Figure 5 Bone metastasis detected only on positron emission tomography/computed tomography in a 47-year-old man who underwent gastrectomy for advanced gastric cancer 16 mo prior. A: Contrast-enhanced abdominal computed tomography showing the absence of bone lesions; B: Positron emission tomography/computed tomography image at the same level showing multiple hypermetabolic lesions in the pelvic bones and sacrum.
