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

Key Points

• 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.
