From: Imaging spectrum of renal oncocytomas: a pictorial review with pathologic correlation
A 74-year-old woman with multifocal renal oncocytomas. a The axial T2-weighted FSE MR image with fat saturation shows two heterogeneous masses in the right kidney (arrows). The tumours consist of a mixture of intermediate (small arrow) and high signal (asterisk) components. b The axial diffusion weighted image (b factor = 800) shows the area of moderate signal on the T2-weighted image to be relatively high signal (arrow), suggesting increased cellularity. c The arterial phase of the axial T1-weighted GRE image with fat saturation demonstrates the area of intermediate signal on the T2-weighted image to be hypervascular (arrow). d Post-contrast coronal T1-weighted GRE image with fat saturation shows partial enhancement in the area of increased signal on the T2-weighted image (arrow)
