Maximum-intensity projection 18F-FDG–PET/CT images. Baseline image showed multiple supra- and infradiaphragmatic nodal lesions and extranodal lesions in breast, intestines, and bone marrow (left); 18F-FDG–PET/CT after 4 cycles of therapy showed a complete metabolic response in all nodal and extranodal lesions, with the exception of limited residual hypermetabolic lesions in the intestinal tract adjacent to the kidney transplant in the right iliac fossa (right). 18F, radionuclide fluorine 18; FDG, fluorodeoxyglucose; PET, positron emission tomography; CT, computed tomography.
