Images of the left kidney tumor. (A) Ultrasonography showing a solid tumor in the left kidney. The tumor borders were clear, and the tumor measured 11 × 10 × 8 cm. We detected mixed echogenicity inside the tumor. (B) Contrast-enhanced computed tomography showing a solid tumor with clear borders and contrasted disproportionate, with no lymph node swelling or tumor embolism. (C) Magnetic resonance imaging (T2-weighted) showing necrosis and hemorrhage inside the tumor. The tumor was suspected to have originated from left kidney tissue (arrow; normal kidney).
