FIGURE 2. A 47-y-old woman with poorly differentiated adenocarcinoma of stomach (linitis plastica type), 6 mo after sub-total gastrectomy, with persistent nausea and vomiting, referred for exclusion of disease recurrence. ¹⁸F-FDG PET scan, coronal section, demonstrates metabolic pattern characteristic of diffuse peritoneal carcinomatosis with uniform low-grade ¹⁸F-FDG uptake throughout entire abdomen and pelvis obscuring normal, discrete, visceral outlines, particularly bowel, liver, and spleen. Her demise was precipitated by gastric outlet obstruction and progressive cachexia.
