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.
