A 41-year-old woman presented with abdominal distention, inappetence, and rapid emaciation for 1 month. Diffuse bulky gastric wall thickening with lymph nodes enlargement and peritoneal nodules were revealed using abdominal CT. Staging 18F-FDG PET/CT performed after admission demonstrated intensely diffuse FDG uptake in stomach, FDG-avid lymph nodes, and peritoneal nodular lesions. Postoperatively, these lesions were diagnosed as diffuse large B-cell lymphoma.
