18F-FDG PET/CT imaging for a gastrointestinal mantle cell lymphoma with multiple lymphomatous polyposis

Figure 2 Images of atypical type multiple lymphomatous polyposis. A, B, D, F, H: [fluorine-18]-fluorodeoxy-glucose -positron emission tomography/computed tomography: (A) Uptake in the gastrointestinal tract was noted at the 4 sites shown in longitudinal images. The SUVmax was 5.1, 6.9, 7.7, and 6.5 in the duodenal bulb (B), rectum (D), ascending colon (F), and cecum (H), respectively; C: Gastrointestinal endoscopy: Three large tumorous lesions circumferentially surrounding the duodenal bulb were observed; E, G: Colonoscopy: Multiple larger nodules than usual type MLP were observed in the rectum (E). The ascending colon was intussuscepted due to a large tumor (G); I: X-ray imaging of the ascending colon and cecum: Large tumorous lesions were observed in the ascending colon and cecum (arrowheads).
