August 2017 – Cross-Fused Renal Ectopia
This 60 year-old patient had a CT scan performed to rule out mesenteric ischemia (inadequate blood flow to the small intestine). The CT scan was ordered as a result of the patient reporting multiple episodes of sharp abdominal pain over the last two years. While there were no findings suggesting mesenteric ischemia, there was an incidental finding of a right-sided cross-fused renal ectopia (fused kidneys located in the right side of the abdomen), demonstrated in the Volume Rendered animation above. This anatomical abnormality is thought to occur during the first trimester and results in abnormal positioning of bowel in the area of where the kidney was supposed to be. The Volume Rendered animation below demonstrates normal kidney positioning.
