Presenting autopsy case was stillbirth in 31 + 1 gestational week. In postmortem autopsy, viewed through the capsule, the renal surface was filled by innumerable miniature cysts about 1 mm in diameter. istopathological examination revealed multiple cysts of variable size in the renal medulla and tortuosity, elongation of ductal plate of liver.
