“…Different classifications of the AL are documented in the literature. One such classification recognizes three broad types based on the gross anatomical connection of AL to the liver: (1) AL attached to the liver via a stalk; (2) AL representing a tongue-like projection of the anterior edge of the liver without a defined stalk (Riedel’s lobe); and (3) ectopic AL located outside the liver without any connections to the liver [6,7]. Another classification system takes into account the different anatomical variants of the connection between the AL bile duct and the intrahepatic or extrahepatic main biliary tree: (1) AL with a separate accessory lobe duct draining into an intrahepatic bile duct of the liver; (2) AL with a separate accessory lobe duct draining into an extrahepatic bile duct of the liver; and (3) AL with a common capsule with the normal liver and the bile duct draining into an extrahepatic duct [8].…”

Accessory Liver Lobe Attached to the Wall of the Gallbladder

A 47-year-old woman with a history of known gallstone disease presented with worsening post-prandial right upper abdominal pain radiating to the back, abdominal bloating, and nausea. An ultrasound of the abdomen confirmed the diagnosis of cholelithiasis. During laparoscopic cholecystectomy, an accessory liver lobe attached to the anterior wall of the gallbladder was incidentally found. An accessory liver lobe is a rare anatomical variation that mostly remains clinically asymptomatic. Since hepatocellular carcinoma can rarely develop in an accessory liver lobe, intraoperative complete resection should be considered for both therapeutic and diagnostic purposes.

“…If continuity with the liver is not present, this abnormality is defined as an ectopic liver. 1,5 ALL is a rare entity, usually asymptomatic, and found during autopsy, surgery (laparotomy/laparoscopy), or abdominal imaging performed for other reasons. 3,6,7 In a recent study on congenital anomalies of the liver observed during laparoscopic exploration, an incidence of 0.44% of ALL has been estimated.…”

“…3 Among the possible complications of ALL, torsion of the pedicle is the most serious, and very few cases have been reported. 4,5 Twisted ALL is associated with abdominal pain and/or impaired liver function, which may be confused with an acute surgical emergency or a tumoral mass. Imaging results are often inconclusive, and an exploratory laparotomy is generally required for a definitive diagnosis.…”

Accessory liver lobe (ALL) is a rare congenital abnormality characterized by the presence of hepatic tissue outside of, but attached to, the liver. ALL is usually asymptomatic, but in the case of torsion, it can be confused with an acute surgical emergency or a tumoral mass. Conventional imaging is often inconclusive, and diagnosis is generally made during laparotomy. We report the case of a patient with left ALL torsion who, for the first time, was successfully diagnosed and treated with a laparoscopic resection.
