Prenatal diagnosis of Meckel-Gruber syndrome case reports.
Two cases of Meckel-Gruber syndrome are presented. In the first case, abdominal tumor and decreased amniotic fluid were initially suspected. In the second case, Omphalocele was diagnosed by local practitioners. Thorough obstetric sonographic studies revealed encephalocele, bilateral renal cystic dysplasia, polydactyly, microcephalus, intrauterine growth retardation (IUGR) and oligohydramnios. Chromosomal analysis by percutaneous umbilical cord blood sampling (PUBS) was normal with 46,XY in Case 1 and 46,XX in Case 2. The prenatal diagnoses were confirmed by autopsy. The pathologic reports revealed type I polycystic kidney, bile duct proliferation, fibrosis of the portal area, encephalocele and polydactyly. It is interesting to note that the two cases came from two different families without any family history of inherited disease.
