Figure 2. (a) Gradient echo (GRE) T₁ weighted axial image shows a hypointense mass (M) in the right paracaval location. (b) GRE fat saturated T₂ weighted axial image shows that the mass (M) is predominantly hypointense with few hyperintense foci in the periphery. (c) Tru-FISP coronal T₂ weighted scan shows that the mass (M) is intimately related to right kidney (K) and is encasing the right ureter and compressing the inferior vena cava (IVC). (d) GRE post-contrast T₁ weighted coronal scan shows an enhancing mass (M) abutting the right kidney (K) causing upstream hydronephrosis.
