Insights
A rare case of right renal ectopia with malrotation and bilateral triple renal arteries was discovered incidentally. This finding highlights the importance of recognizing congenital renal variations during imaging for surgical planning.
Area of Science:
- Anatomical variations in human urogenital system
- Medical imaging and diagnostics
Background:
- Congenital renal ectopia, a displacement of the kidney from its normal position, is a rare condition.
- Variations in renal vasculature, including accessory renal arteries, are also uncommon congenital anomalies.
Observation:
- A 64-year-old male patient presented with incidentally discovered right renal ectopia and malrotation.
- CT angiography revealed bilateral triple renal arteries, with one main and two accessory arteries originating from the abdominal aorta.
- The renal arteries were symmetrically disposed and of equal caliber.
Findings:
- The case demonstrates a rare combination of renal ectopia, malrotation, and complex bilateral renal vascular variations.
- The incidence of simple renal ectopia is low, with many cases diagnosed incidentally.
Implications:
- Accurate identification of renal position and vascular variants is crucial for surgical interventions and managing potential complications.
- CT angiography is a valuable tool for diagnosing such anatomical variations, aiding in clinical decision-making.
Abstract:
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.

External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
