Laparoscopic resection of solitary congenital liver cyst in a neonate.

Solitary congenital liver cysts are a rare finding and present a challenge in the diagnosis. Routine prenatal ultrasounds confirmed the presence of an isolated cystic mass in the upper abdominal cavity of a fetus during the third trimester of gestation. Ultrasound examination performed after birth confirmed the presence of a floating cyst in the upper abdomen. Laparoscopy was performed on the 12th day to confirm the diagnosis using a 2.7 mm scope and instruments. Using a monopolar hooked cautery, the cyst was resected free from the liver surface without any complication. The postoperative course was uneventful. Histopathologic analysis demonstrated a true liver cyst with a mesothelial lining and hepatic residues. To our knowledge, this is the first case reported in literature where a solitary liver cyst was resected using minimal invasive techniques in a newborn.
