Diagnostic role of 18F-fluorodeoxyglucose positron emission tomography for follicular lymphoma with gastrointestinal involvement

Figure 5 A 37-year-old female patient with systemic follicular lymphoma and extended gastrointestinal involvement from the duodenum to the rectum (stage IV, grade 1). A: An esophagogastroduodenoscopy detected small whitish nodules present in the duodenum; B, C: A colonoscopy revealed multiple polyps present in the ileum (B), cecum, colon (C), and rectum. Jejunal involvement was confirmed by video capsule endoscopy; D: During 18F-fluorodeoxyglucose positron emission tomography, tracer uptake was only noted in the ileum and colon.
