Ectopic kidney with malrotation and bilateral multiple arteries diagnosed using CT angiography.

Right renal ectopia with malrotation was seen on a CT angiography in a 64-year-old male patient. Bilateral triple renal arteries were also revealed: one main (superior) renal artery and two accessory arteries (middle and inferior), all originating in the abdominal aorta. The renal arteries are disposed symmetrically. The main arteries and the accessory ones are of equal caliber. Simple renal ectopia is a congenital malformation with an incidence of 1-2 cases in 1000 births; of these, only one of 10 cases is diagnosed. Like our case, many such cases are diagnosed by accident, during investigations of causes that have no connection with renal ectopia. Variations in kidney position and renal vascular variants are very important clinically, for both the complications they may generate and the technical difficulties of certain surgical interventions. CT angiography is a minimally invasive method that allows the identification of malformations or anatomic variations, providing accurate information on position, size and anatomic ratios, which are very useful in diagnosing and treating various affections.
