Coronal (above left) T2 MRI of the abdomen shows a right-sided heterogenous and hyperintense oval shaped suprarenal retroperitoneal mass that on sagittal T2 MRI (above right) is anterior to the spine (which has an incidental segmentation anomaly at T10-T12) and which on axial T2 MRI (below left) is seen to cross the midline in close proximity to the inferior vena cava and aorta. On axial T1 MRI with contrast (below right) the mass shows some enhancement. Other imaging (not provided) revealed invasion of the inferior vena cava by the mass and lung metastases.
