title: Crossed renal ectopia in a squirrel monkey (Saimiri sciureus) and an owl monkey (Aotus trivirgatus).
abstract: A 5-year-old female squirrel monkey, Saimiri sciureus, died with a ceco-colonic infarct. An incidental finding was renal ectopia: The left kidney was located between the common iliac arteries posterior to the bifurcation of the aorta and to the right of the body midline. An adult owl monkey, Aotus trivirgatus, was killed in renal failure due to end-stage glomerulonephritis. Fused kidneys were located on the right side and posterior to the normal position. These are examples of crossed renal ectopia with and without fusion.
