Solitary Septated Simple Liver Cyst in a Newborn Infant

Area of Science:

• Pediatric Surgery
• Hepatobiliary Medicine
• Neonatal Imaging

Background:

• Simple liver cysts (SLC) are uncommon in neonates and often asymptomatic.
• When symptomatic, SLCs can cause significant complications due to mass effect.

Observation:

• A newborn infant presented with a cystic liver lesion detected antenatally via ultrasound and MRI.
• Postnatal imaging confirmed a solitary, septated cystic structure causing biliary and venous obstruction.

Findings:

• The solitary septated simple liver cyst exerted mass effect on the common bile duct and inferior vena cava.
• Laparoscopic total excision was performed as the treatment modality.

Implications:

• Laparoscopic surgery is a viable and effective treatment for symptomatic neonatal simple liver cysts.
• Complete excision led to an uncomplicated recovery and positive long-term outcome for the infant.
