Advances of multidetector computed tomography in the characterization and staging of renal cell carcinoma

Figure 6 The 74-year-old man with synchronous bilateral renal cell carcinomas of clear cell type (stage T1). Bilateral synchronous renal cell carcinomas (RCCs) are uncommon, reported in less than 2% of patients with RCCs. The patient had left radical nephrectomy and right partial nephrectomy. Sagittal multiplanar reformations (MPR) (A) and coronal 3D reformation with volume rendering technique (B) during the corticomedullary phase depict a sharly-demarcated tumor in the lower pole of the left kidney (arrow, A), strongly and heterogeneously enhancing. Sagittal (C) MPR and (D) 3D reformation with the same algorithm depict a second, smaller tumor in the upper pole of the right kidney, with a similar pattern of contrast enhancement. Preoperative information obtained with computed tomography examination enabled conservative surgery for the right renal malignancy.
