Prenatal diagnosis of Meckel syndrome: a case report.
OBJECTIVE
To demonstrate the major sonographic findings associated with Meckel syndrome and to emphasize the importance of prenatal sonography in helping to establish the correct diagnosis.


METHODS
Two fetuses with prenatal diagnosis of Meckel syndrome were sonographically evaluated.


RESULTS
Both fetuses were demonstrated to have evidence of renal cystic dysplasia, occipital cephalocele and postaxial polydactyly. One case was diagnosed at 16 weeks of gestation whereas the other was detected at 36 weeks. Of interest, the first case had only unilateral renal cystic dysplasia and contralateral renal agenesis and mild degree of oligohydramnios. The other related anomalies which were not detected prenatally included cerebellar hypoplasia in case 1 and micrognathia in case 2.


CONCLUSIONS
The main sonographic findings included renal cystic dysplasia, occipital cephalocele and postaxial polydactyly.
