Meckel–Gruber syndrome is a lethal disorder characterized by occipital encephalocele, polycystic kidneys, and polydactyly. In most cases, it is identified and terminated antenatally. In this report, the authors present a case of Meckel–Gruber syndrome together with Dandy–Walker malformation. A pregnant woman referred at the 28th week of gestation with an abnormal ultrasound scan showing posterior encephalocele and bilaterally enlarged kidneys. Further imaging also indicated communication between the 4th ventricle and posterior cerebellar cerebrospinal fluid space, after which the fetus was diagnosed with Meckel–Gruber syndrome and Dandy–Walker malformation. Pregnancy termination was refused by the parents and the offspring was prematurely born to be the 2nd recurrence of Meckel–Gruber syndrome in this consanguine family. Remarkably, at the 3 different pregnancies, ultrasound was inconclusive before the 7th month of gestation. Though up to date Meckel–Gruber syndrome is ultimately lethal, the lifespan of affected newborns varied greatly. We suggest developing a severity classification to estimate life expectancy in unterminated cases.
