[Possibilities of ultrasonic diagnosis in fetal abdominal monstrosities (author's transl)]

The diagnostic possibilities of intrauterine ultrasonic assessment of the fetal abdomen by rapid B-scan are described on the basis of two cases (megalocystis/megaloureter syndrome and omphalocele with cloaca formation). Other examination methods of prenatal diagnosis to confirm the findings are also discussed, but their diagnostic significance is even more limited than that of sonography, individual cases excepted. Although early detection of neural tube anomalies is the most important application of ultrasound, pronounced monstrosities of the fetal abdominal region are also definitely recognisable via ultrasonic examination.
