A case of Hirschsprung disease of total intestinal aganglionosis with intestinal dilatation and peristalsis on prenatal ultrasound

Intestinal dilatation and peristalsis can be detected via prenatal ultrasonography in Hirschsprung disease.
In cases of total intestinal aganglionosis, the aganglionic segment may still show movement.
Detection of these features may aid in earlier diagnosis of Hirschsprung disease during pregnancy.
Implications for prenatal care and monitoring may improve outcomes for affected infants.

Prenatal ultrasonography may reveal fetal intestinal dilatation with intestinal movement like peristalsis in HD, even in the aganglionic portion.
