Evaluation of recurrence in gastric carcinoma: Comparison of contrast-enhanced computed tomography and positron emission tomography/computed tomography

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.
