Presentation
Abdominal pain.
Patient Data
Contrast-enhanced CT shows a right pelvic kidney and a left kidney in normal position. The right renal artery arises from the distal aorta just proximal to the bifurcation with early branching. Two renal veins drain the kidney into the left common iliac vein and directly into the inferior vena cava, respectively. Ureteral drainage into the bladder is normal bilaterally.
An exophytic area of fatty change at the left inferior kidney corresponds to a remote ablation site.
Case Discussion
Pelvic positioning of the kidney is due to failure to ascend in early development around the 9th week of gestation.
