Meckel-Gruber syndrome is a quite rare congenital disorder, characterized by posterior encepalocele, cleft palate and lip, polycystic kidneys, hepatic fibrosis with bile duct proliferation, and postaxial polydactyly and syndactyly. We experienced an autopsy case of M eckel-Gruber syndrome in a second baby of 28 year-old woman. At 26 weeks of gestation, congenital anomaly was detected on ultrasonographic examination and the pregnancy was terminated. Familial history was not noted.
We report an autopsy of a male fetus that showed multiple congenital anomalies that could best be designated as Meckel-Gruber syndrome. The fetus was born dead at the gestational age of 38 weeks. His parents denied any history of congenital malformation. And the parity of the mother was 0-0-0-0, but she had the past history of receiving herb medication for common cold. The congenital anomalies found in this case consited of occipital meningoencephalocele, midline cleft palate, bifid epiglottis, hepatic fibrosis, choledochal cyst, bilateral polycystic kidneys, postaxial polydactyly of both hands and feet, aplasia of the left testis, secundum type atrial septal defect and patent ductus arterious. This malformation syndrome is rare and lethal.
The prenatal diagnosis should be made by ultrasound study or analysis of the amniotic fluid for alpha-feto protein during intrauterine period. The kidneys showed Potter type III cystic change and there was a characteristic hepatic fibrosis.
