Diagnosis of holoprosencephaly before 20 weeks of gestation by imaging is essential in order to avoid the psychological pain of bearing the deformed fetus till term and delivering a still born baby. It is estimated to occur in 1/16,000 live births and 1/250 conceptuses. 2001 May. In vivo diagnosis can be established with prenatal brain imaging and disease severity correlates with extent of abnormally developed brain tissue. CT scanning is best suited for imaging the bony structure of the skull. In 81% of the cases, the diagnosis of HPE was confirmed postnatally. Holoprosencephaly is a kind of brain anomaly characterized by inadequate cleavage of the prosencephalon during early embryogenesis. Ultrasound is a good modality for prenatal diagnosis of holoprosencephaly that is frequently associated with midline face deformity such as cleft lip and palate. The diagnosis was established based on high levels of 7-dehydrocholesterol (7DHC) and 8-dehydrocholesterol (8DHC) in amniotic fluid. This site needs JavaScript to work properly. Epub 2019 Dec 16.
