A 65-year-old man with history of MALT lymphoma treated with rituximab with new onset fever and fatigue. a Coronal reconstructed CT image acquired during portal venous phase at time of diagnosis shows a large mass at the ascending colon (arrow). Biopsy of the mass demonstrated MALT lymphoma. b Coronal reconstructed CT image after 6 months of treatment shows resolution of the mass. c PET/CT axial fused image at new onset of symptoms shows intense focal FDG uptake in the region of the ileocecal valve with SUVmax 15.9. Biopsy of the mass showed histologic transformation to diffuse large B cell lymphoma
