OBJECTIVE To examine the potential value of routine measurement of cervical length in singleton pregnancies at 23 weeks of gestation in the prediction of the risk for early spontaneous preterm delivery. METHODS Cervical length was measured by sonography at 23 weeks in 2567 singleton pregnancies in women attending for routine antenatal care. In 43 women, the length was < or = 15 mm and 21 of t...

Walker-Warburg syndrome (WWS) is a rare and lethal autosomal recessive disorder, caused by defective glycosylation of α-dystroglycan that is important for muscle integrity and neuronal migration. Mutations in six genes involved in the glycosylation of α-dystroglycan (POMT1, POMT2, POMGNT1, FCMD, FKRP and LARGE) have been identified in WWS patients, and others remain under study. Prenatal diagno...

Achondrogenesis is a lethal form of congenital chondrodystrophy characterized by extreme micromelia. We describe a case of achondrogenesis type II (Langer-Saldino achondrogenesis) detected by prenatal ultrasonography at 20-week gestation. A dwarfed fetus with large head, short neck and chest, prominent abdomen and short limbs was terminated transvaginally. Radiologic and histopathologic examina...

Congenital cystic adenomatoid malformation (CCAM) is a rare pulmonary malformation resulting from excessive overgrowth of the terminal bronchioles. We present two CCAM case studies: type I (macrocystic) and type III (microcystic), diagnosed by antenatal ultrasonography at 31 and 21 weeks' gestation, respectively. In the former, multiple dilated cystic masses in the fetal left lung, with polyhyd...

Treacher-Collins syndrome (TCS) is a rare dominant autosomal anomaly resulting from malformation or disruption of the development of the first and second branchial arches. It is characterized by micrognathia, malar hypoplasia, and malformations of the eyes and ears. The prenatal diagnosis using two-dimensional ultrasonography (2DUS) is characterized by identification of facial malformations tog...
