Inflammatory aneurysms (arrow) have a large perianeurysmal inflammatory mass. These aneurysms frequently require suprarenal aortic control and are often best managed via a retroperitoneal exposure. Therefore, recognizing them preoperatively allows planning.
Congenital variations in renal anatomy are important findings on the CT scan. Renal ectopia and renal fusion create difficulties both with exposure and due to aberrant blood supply and ureteral drainage. These CT images demonstrate crossed renal ectopia with the two kidneys fused on the patient's right.
