  • Figure 1
    CT appearance of bilateral renal cell carcinoma

    On contrast-enhanced axial CT section, the right kidney contains an isodense mass lesion protruding from the renal cortex and extending to the renal pelvis and hilum with eccentric necrosis. The lesion in the left...

    MR imaging findings in bilateral renal cell carcinoma
     

    Spin-echo T1-weighted MR image shows a mass lesion protruding from the right renal cortex.

     
    Area of Interest: unknown; Imaging Technique: MR imaging findings in bilateral renal cell carcinoma;

    Spin-echo T1-weighted MR image through the upper pole of the left kidney shows a hypointense mass lesion.

     
    Area of Interest: unknown; Imaging Technique: MR imaging findings in bilateral renal cell carcinoma;

    Gradient-echo T2-weighted MR image shows heterogeneous increased signals within the lesion of the right kidney.

     
    Area of Interest: unknown; Imaging Technique: MR imaging findings in bilateral renal cell carcinoma;

    Contrast-enhanced T1-weighted MR image shows prominent contrast enhancement in the lesion of the right kidney. Necrotic components become more significant.

     
    Area of Interest: unknown; Imaging Technique: MR imaging findings in bilateral renal cell carcinoma;

    Contrast-enhanced T1-weighted MR image better shows the internal septations within the lesion of the left kidney. Note also mural nodule enhancement on the anterolateral border of the lesion.

On contrast-enhanced axial CT section, the right kidney contains an isodense mass lesion protruding from the renal cortex and extending to the renal pelvis and hilum with eccentric necrosis. The lesion in the left kidney is hypodense with thin internal septations.
