  • Figure 1
    Plain CT of the abdomen

    Plain CT of the abdomen showing a well-defined, solid, mildly and homogeneously hyperdense formation in the right kidney.

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    CT of the abdomen; arterial phase

    The solid formation shows strong and mildly inhomogeneous enhancement with some vascular intralesional elements.

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    CT of the abdomen; venous phase

    The solid formation is inhomogeneously hypodense compared to the renal parenchyma.

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    CT of the abdomen; late excretory phase

    In the pelvis of the right kidney a solid hypodense formation is evident, causing extrinsic compression and displacing the pelvicalyceal system.

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 5
    CT of the abdomen; late excretory phase

    Coronal MIP reconstructions; the formation causes displacement of the pelvicalyceal system without CT signs of infiltration.

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 6
    Macroscopic finding
