Figure 1 Computed tomography imaging of the patient. A: Volume representation shows bilateral multiple renal tumors (4 masses); B: Pre-operative axial computed tomography (CT) imaging sections showing a 1.9 cm × 1.9 cm × 2.0 cm tumor arising from the right kidney, exophytic, heterogeneous hypodense, without calcification and hemorrhage, proven to be chromophobe renal cell carcinoma (orange arrow); C: Axial CT imaging sections showing a 3.3 cm × 3.2 cm × 2.9 cm tumor arising from the left kidney, exophytic, homogeneous isodense, without calcification and hemorrhage, proven to be a chromophobe renal cell carcinoma (orange arrow); and D: Axial CT imaging sections showing a 1.4 cm × 1.3 cm × 1.1 cm tumor arising from the right kidney, homogeneous hyperdense, without calcification and hemorrhage, proven to be a clear cell renal cell carcinoma (orange arrow).
