Variation of right renal artery duplication with retroaortic left renal vein: a case report

Abstract

Variations of renal arteries and veins are of particular importance in the treatment of renal and renovascular conditions. Multiphase upper abdominal computed tomography of a 68-year-old male patient with renal cell carcinoma of right kidney revealed duplication of right renal artery and retroaortic left renal vein variation. Differential diagnosis should be made with great care in patients with renal neoplasms since variations may complicate diagnostic procedures. Here, we present a rare variation. Knowledge of variations accompanied by pathologies as in our case may be important as it can affect diagnostic and treatment procedures. The aim of this case report and literature review is to increase awareness about renal vascular variations among clinicians and oncologists who work in this field.
