Insights
Prenatal diagnosis of congenital biliary cysts is possible via ultrasonography. Surgical intervention is essential for accurate diagnosis and to prevent complications from these rare fetal abdominal cysts.
Area of Science:
- Medical Imaging
- Pediatric Surgery
- Fetal Medicine
Background:
- Congenital biliary cysts are rare cystic malformations of the biliary system.
- Prenatal detection of these cysts presents diagnostic challenges.
Purpose of the Study:
- To report two cases of prenatal detection of congenital biliary cysts.
- To discuss the diagnostic considerations and treatment of fetal abdominal cystic lesions.
Main Methods:
- Utilized prenatal and postnatal ultrasonography to visualize cystic lesions.
- Reviewed differential diagnoses for abdominal cystic lesions in fetuses and infants.
Main Results:
- Both cases presented as solitary sonolucent cystic lesions.
- Ultrasonography was key in identifying the cystic nature of the lesion.
Conclusions:
- Accurate prenatal diagnosis of congenital biliary cysts is achievable with ultrasonography.
- Surgical management is the definitive treatment for histological confirmation and complication prevention.
Abstract:
Two cases of prenatal detection of congenital biliary cysts are reported. Prenatal and postnatal ultrasonography demonstrate a solitary sonolucent cystic lesion. The differential diagnosis in fetus and infant includes any abdominal cystic lesions: ovarian cyst, duplication cyst, cystic lymphangioma, choledochal cyst and other congenital cysts of the liver. In opposite to the difficulty of diagnosis, the choice for treatment is easy: surgery is the only way to allow histologic diagnosis and to avoid any relapse or complications.
