Prenatal Diagnosis of Monosomy 17p (17p 13.3 → pter) Associated With Polyhydramnios, Intrauterine Growth Restriction, Ventriculomegaly, and Miller-Dieker Lissencephaly Syndrome in a Fetus

Polyhydramnios, IUGR and ventriculomegaly are important prenatal ultrasound markers of MDLS. Prenatal diagnosis of these markers should include a detailed investigation of cerebral sulci and fissures, and genetic analysis for MDLS. Fetal MRI is helpful for the diagnosis of lissencephaly.
