  • Figure 1
    Unenhanced CT abdomen
     

    A large, relatively well-defined, lobulated, predominantly hyperdense lesion (red arrow), involving almost entire left kidney with maintenance of its reniform shape.

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Left renal staghorn calculus was also noted (yellow arrow).

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;
     
     
  • Figure 2
    Post-contrast venous phase abdomen
     

    On post-contrast venous phase, the renal lesion showed mild homogeneous enhancement. No evidence of internal necrosis was noted. (red arrow)

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Similar characteristic soft tissue thickening was also noted along bilateral ureters up to lower end (red arrows).

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Coronal section demonstrating bulky left renal mass (yellow arrow), soft tissue thickening around ureter (red arrows), within urinary bladder (blue arrow).

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Soft tissue thickening within urinary bladder (yellow arrow).

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;
     
     
  • Figure 3
    Delayed scan

    On 1-hour delayed scan, contrast excretion was noted in right kidney (yellow arrow) but was not noted in left kidney (red arrow).

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;
     
     
  • Figure 4
    MRI abdomen T2-weighted axial image
     

    The above mentioned left renal lesion appeared hypointense on T2 weighted images with no evidence of necrosis within it (red arrow).

     
    Area of Interest: Kidney; Imaging Technique: MR; Procedure: Education; Special Focus: Lymphoma;

    The above mentioned soft tissue peri-ureteral thickening appeared hypointense on T2 weighted images with no evidence of necrosis within it (yellow arrows).
