Patient
female, 89 year(s)
 
 
  • Figure 1
    Ultrasound B mode

    Ultrasonography demonstrating homogeneous thickening of the right half of the urinary bladder (arrows), obliterating the vesico-ureteral junction.

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 2
    CT scan

    CT scan in (axial plane), nephrogenic phase after iv contrast, shows thickening and intense contrast attenuation of the internal margin of the bladder (arrows), the muscular layer (W) enhances less and is markedly...

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Inflammation;
     
     
  • Figure 3
    T2-weighted MRI

    T2-weighted MRI showing diffused thickening of the right lateral half of the urinary bladder wall with low and high signal intensities on luminal and peripheral sides, respectively. The luminal surface appears irregular.

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Inflammation;
     
     
  • Figure 4
    T1-weighted MRI image

    T1-weighted image with fat saturation, after IV contrast. Enhancement of the inner side of the thickened bladder wall is seen, as well as some focal enhancement of the deeper muscular layer.

    High-resolution haematoxylin and eosin staining of bladder wall

    High-resolution haematoxylin and eosin staining of bladder wall biopsy of the patient; abundant eosinophils were observed in the submucosa consistent with those observed in non-tumoural eosinophilic cystitis.
