<p>(a) B0 image. (b) Diffusion-weighted image with b value 800 s/mm<sup>2</sup> showed the hyperintensity tumor, but it was not able to depict diffuse spleen involvement. (c) The corresponding ADC map showed the hypointensity tumor with ADC<sub>min</sub> 0.34×10<sup>−3</sup> mm<sup>2</sup>/s and ADC<sub>mean</sub> 0.68×10<sup>−3</sup> mm<sup>2</sup>/s. (d) Axial CT image. (e) FDG-PET image. (f) The fused PET/CT image showed the active tumor and spleen involvement with SUV<sub>max</sub> 23.9.</p
