Adult polycystic kidney disease in a rhesus monkey (Macaca mulatta)

Adult polycystic kidney disease was diagnosed at necropsy in a 16-year-old rhesus monkey dead from renal failure. Both kidneys were enlarged and contained multiple cysts ranging from 0.1 to 4.0 cm in diameter. The age of onset of the clinical signs, terminal uremia, and the gross and histologic findings in this macaque were consistent with adult (type III) polycystic kidney disease of man.
