Fig. 2 Abdominal CT, from left to right, top to bottom: unenhanced scan, contrast-enhanced scan in portal phase on the coronal plane, arterial phase, portal phase. A hypervascular mass is seen displacing the right kidney, with a hypodense center (*), compatible with necrosis.

Fig. 3 MIBG I123 scintigraphic scan with SPECT-CT. The lesion is marked with the yellow arrow, not showing any kind of uptake of MIBG I123. European Journal of Radiology Open 2017 4, 9-12DOI: (10.1016/j.ejro.2017.01.003) Copyright © 2017 The Author(s) Terms and Conditions

Fig. 4 MR study, on the left T2WI acquired in singleshot, on the right top to bottom: T2 with fat saturation, DWI-b1000, ADC map. As with the CT images, a mass is seen displacing the right kidney, with very hyperintense center (necrosis) and very high diffusion restriction in the solid portion of the mass.
