Infantile polycystic renal disease in a rhesus monkey (Macaca mulatta)

Congenital infantile polycystic renal disease was diagnosed in the infant rhesus monkey. The kidneys were enlarged, and renal tubules were cystic. The intrahepatic bile ducts were increased in number, dilated, and surrounded by excessive fibrous tissue. This disease was similar to inherited infantile polycystic renal disease in man.
