  • Figure 1
    Initial contrast-enhanced multidetector CT
     

    Both kidneys show normal, symmetric size and parenchymal thickness, homogeneous enhancement in the nephrographic phase. On the right, minimal perinephric and pararenal fluid effusion (*) is noted.

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Colonography CT; Special Focus: Infection;

    On the right, minimal perinephric and pararenal fluid effusion (*) is noted. The ipsilateral renal pelvis shows mild, circumferential mural thickening with urothelial hyperenhancement (arrowhead).

    Post-treatment follow-up multidetector CT
     

    After clinical and laboratory improvement, follow-up MDCT shows resolution of perinephric and pararenal effusion, and regression of right pyelo-ureteral thickening and hyperenhancement.

     
    Area of Interest: Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Colonography CT; Special Focus: Infection;

    After clinical and laboratory improvement, follow-up MDCT shows resolution of perinephric and pararenal effusion, with normal parenchymal enhancement and collecting system opacification.
