Visualization of a Y-configuration and peristalsis on prenatal sonography: The pathognomonic sign of an ileal duplication cyst

Key Points

• Accurate diagnosis of ileal duplication cyst by prenatal sonography is crucial for early intervention.
• Laparoscopic-assisted surgical treatment can be performed before symptom onset, reducing complications.
• The Y-configuration and peristalsis observed on sonography serve as pathognomonic signs.
• Timely detection and treatment can significantly improve outcomes for newborns.
