Congenital Hepatic Cyst.

Area of Science:

• Pediatric Surgery
• Hepatology
• Medical Imaging

Background:

• Congenital hepatic cysts are rare, typically asymptomatic liver lesions in infants and children.
• Incidence is higher postnatally (2.5%) than prenatally.
• Antenatal imaging frequently reveals these cysts as incidental findings.

Observation:

• A case of a newborn with a fetal liver cyst detected via ultrasound is presented.
• Postnatal imaging confirmed a right lobe liver cyst without affecting other intrahepatic structures.
• The infant was asymptomatic despite abnormal liver function tests.

Findings:

• Follow-up imaging demonstrated a slight decrease in the cyst's size.
• Conservative management with serial ultrasound monitoring is standard.
• Surgical intervention is indicated for complications like hydrops, enlargement, hemorrhage, torsion, or compression.

Implications:

• This case highlights the importance of antenatal diagnosis and postnatal monitoring of congenital hepatic cysts.
• While malignant transformation is exceptionally rare, surgical options exist for large or complicated neonatal lesions.
• Understanding management strategies ensures optimal outcomes for affected infants.
