a Contrast-enhanced computed tomography findings. Multiple mass lesions of low density are noted in the arterial phase. b Findings of dynamic magnetic resonance imaging in the early arterial phase. The mass lesions show low signal intensities. c Findings of dynamic magnetic resonance imaging in the equilibrium phase. The mass lesions show signal isointensities. d Positron-emission tomography computed tomography findings. Image shows splenomegaly without an abnormal uptake
