MKS, Meckel Gruber syndrome is a rare, lethal, genetic multiple congenital anomaly characterized by the following triad: cerebral malformation (primarily occipital encephalocele), polycystic kidneys, and polydactyly, as well as associated abnormalities that may include cleft lip/palate, cardiac and genital abnormalities, central nervous system (CNS) malformations, hepatic fibrosis, and bone dysplasia. The mode of transmission of MKS is autosomal recessive. Genetic counseling should be offered to couples at risk. MKS is lethal in utero or in the very early neonatal period, with pulmonary hypoplasia and renal failure being the main causes of early death. Our case illustrates the importance of prenatal diagnosis, essentially by ultrasound, in order to ensure adequate management.
