Patient
male, 32 year(s)
 
 
  • Figure 1
    Coronal reformatted, contrast enhanced CT

    There are bilateral ectopic kidneys. The left kidney lies in the presacral space and the right kidney is in the upper pelvis.

     
     
     
  • Figure 2
    Axial contrast enhanced CT
     

    The right kidney has duplex proximal ureters (arrowheads).

     

    The duplex proximal ureters fuse just below the renal pelvis (arrowhead).

     
     
     
  • Figure 3
    Coronal reformatted, contrast enhanced CT

    The ectopic right kidney has an anomalous blood supply consisting of multiple renal arteries originating just above the aortic bifurcation. This is a consequence of arrested ascent during embryonic development.

     
     
     
  • Figure 4
    Intravenous pyelogram

    There is complete duplication on the anatomic right side and partial duplication to the level of the UPJ on the left side.
