Meckel-Gruber syndrome is a congenital disorder characterized by occipital encephalocele, bilateral multicystic kidneys with fibrotic changes of the liver and postaxial polydactyly. Other anomalies are frequently associated. This syndrome is a rare autosomal recessive disorder often resulting in neonatal death within a few hours of life and has the high recurrence(one in four) in future pregnancies. We present the case of Meckel-Gruber syndrome diagnosed by ultrasonography at 18 weeks` gestation with a brief literature review.
