male, 45 year(s)
 
 
  • Figure 1
    Perirenal idiopathic retroperitoneal fibrosis
     

    Axial T1-weighted image shows sharply defined intermediate tissue encasing the right ureter and kidney

     
    Area of Interest: unknown; Imaging Technique: Perirenal idiopathic retroperitoneal fibrosis;

    Perirenal lesion is heterogeneous, with hypointense and hyperintense areas on T2-weighted image

     
    Area of Interest: unknown; Imaging Technique: Perirenal idiopathic retroperitoneal fibrosis;

    Gd-DTPA enhanced T1-weighted axial MR image shows slight peripheral enhancement

     
    Area of Interest: unknown; Imaging Technique: Perirenal idiopathic retroperitoneal fibrosis;

    Gd-DTPA enhanced T1-weighted coronal MR image shows a soft tissue lesion encasing the right kidney and inferior vena cava with slight peripheral enhancement
