Axial T2-weighted projection shows a left renal tumor with heterogeneous enhancement in the upper pole, dilated ipsilateral renal vein with absence of flow void in its most proximal portion.
DWI and ADC projections show partial diffusion restriction of the left renal tumor. Renal vein shows no obvious diffusion restriction.
Axial T1-weighted projection with intravenous contrast in late phase shows heterogeneous enhancement of a tumor in the left renal upper pole with a filling defect in ipsilateral renal vein without enhancement.
