RESUMO
We report a case of aneurysm of the umbilical vein, causing fetal death at 41 weeks gestation. We conclude that these aneurysms are a complication of congenital thinning of the vessel wall and want to emphasize that in stillbirths the cause of death may only be revealed by careful placental examination, including the umbilical cord.

Three infants with nonobstructive bile duct dilatation (Caroli disease) are described. The bile duct pathology was associated with autosomal recessive polycystic kidney disease in two patients and with severe destruction of the renal parenchyma of unknown origin in the other. Sonograms of the liver showed, besides bile duct dilatations, intraluminal bulbar protrusions, bridge formation across dilated lumina, and portal radicles partially or completely surrounded by dilated bile ducts. Liver biopsy was performed in two patients, and in one patient, the biopsy sample confirmed the findings noted on sonograms. These findings support the hypothesis that the normal embryogenesis of intrahepatic bile ducts is arrested in the pathogenesis of this disease.
